Coda

LHN - I'd be interested to know what graphics card you have, and what gfx settings your KSP has.

Ok, so an update. Changing to half-res textures fixed the hanging. I can play for hours now without a crash. I would like to have full-res textures back, so I'll have a look at that ATM thing. Thanks a lot for your help guys, especially as it's the holiday season. Edit: 6 hours later, a hang when clicking launch. So, the texture settings just highlighted a problem with memory management. With lower-res textures I can play for longer but obviously the problem still exists. Edit 2: I installed Automatic Texture Management, and the problem still exists. I'm getting hangs about 1 hour into playing. Removed ATM and went back to half-res textures, so I can actually use KSP for a few hours at a stretch...

It was on, I've turned it off now, and the gfx glitches seem to have gone <crosses fingers>. Yep http://en.wikipedia.org/wiki/Spinning_pinwheel - I have to force quit it. Thanks for your help so far, Master Tao and steve_v. I'll post back on my findings as I test some more. Edit: Another hang. Playing since I posted this message, so it's been about 30 odd minutes. GFX glitches haven't reappeared though.

Thanks for the reply steve_v. The Beachball of Death isn't an OS crash, but an app crash. I have to force-close KSP (like CTRL-ALT-DELETE, run process manager, close process) at which point I can re-start KSP. I have a windows partition on this computer, and I have done numerous stress tests in the past and other games (Win or OSX) on maximum settings don't give any problems. Therefore, I don't feel that it's likely to be a hardware issue. Also, when running KSP on OS X, the system is not behaving like it is stressed, the fans are still quiet. When the system is loaded running other apps or games whether on (Win7 or OSX) they can get quite loud. You can definitely tell when the system's working hard. Most crashes seem to happen when clicking on Launch after building a rocket or changing scene/building. After having thought about it for a while, I think there are two separate issues. a) Out of memory errors leading to a crash (as evidenced by malloc fails) and GFX Glitches (maybe they are caused by these particular Apple/nVidia supplied gfx drivers, but I didn't see these glitches before with this exact same machine and OS version, up until 0.90). Thanks.

That's a lot of time spent for something that almost definitely isn't Mavericks' fault, and I certainly don't want to go to 10.10, it's a downgrade, not an upgrade.

Since upgrading to 0.90 I'm getting quite a lot of crashes. The feeling is that stability seems to have gone backwards for me, it was pretty stable on the 0.25.x builds (unless loading more than a couple of mods). However, this time I had a vanilla install with just Mechjeb and HyperEdit installed. First thing I started seeing was weird graphics glitches whenever the mouse is hovering over the staging bar (or whatever that's called), then eventually after some playing I'll get spinning beachball of death. Logs show Malloc problems, it looks like a memory leak to me. Anyway, I removed both Mechjeb and HyperEdit, and problems did not go away. I re-installed MJ and continued to play. However, it's really starting to get on my nerves now as I get a maximum of maybe one hour before a crash (sometimes only 10-15 minutes). I havenn't booted into windows to try 0.90 yet, but I feel that all versions of KSP that I have used (since 0.18 or so) were more stable on Windows than on OS X. Maybe it's my settings, or my machine, and not the OS X branch of KSP? Mac Pro, 16GB, Nvidia 590GTX, OS X 10.9.4. https://www.dropbox.com/s/h1i443jnoxdcw1l/Player.log?dl=1 https://www.dropbox.com/s/ghaobxrkcxuwh0p/KSP.log?dl=1 https://www.dropbox.com/s/yecvz6iysh3wlxy/settings.cfg?dl=1

KMP is in constant development, and your post sounds to me like you're thinking your experience is the norm. It isn't. I've used KMP for a couple of weeks without experiencing anything like that.

I'd personally like to see a tool that can take a single player save and convert it into a server db. Useful for when you want to build a 'scenario' and then make it public for people to play. Also, I'd some optimisation of the '/' server commands would be nice. At the moment they are quite awkward to use (/listships could be /ls) and there isn't any autocomplete or shortcuts (i.e. you could type /lists, /listsh, /listshi etc for /listships, but not /list because it's ambiguous due to /listclients). I have quite a few more ideas but I guess if I start thinking about it too much I should rather do a clone and start coding :-)

I noticed that I cannot reach http://godarklight.kerbalcentral.com:82/kmp/index.php today. Will it come back?

I have several Macs at home, about half of them are hackintoshes. My main KSP machine (see how I'm keeping on-topic? ) is an i7 with 590GTX and 16GB ram. Most of the time I'm running it in Mac mode (because I have several desktops running with email, study materials, VNC clients etc at the same time with KSP). I find that under W7 on the same machine, KSP is a lot quicker, probably because of the better nVidia drivers. Otherwise, most games I play I stay on the mac, they are either native games, or some version of wine ports. If they are not the latest games, they usually run full speed and it's convenient for me to be able to alt-tab to do some work. Yeah I think that's driven by the industry, as you can buy PCs that will run photoshop a lot cheaper than the cheapest mac. The thing is, creativity also stretches to music and other types of art and design which the PC can lack in some cases the tools (not quantity necessarily, but quality). I am a musician and I use another hackintosh in another room for writing and recording music. Apart from one of my main programs which is mac specific, all of the rest are also PC available (like ableton live, reaper etc). I did go through a phase last year of trying several linux distro's geared towards music production (Av linux, ubuntu studio, CCRMA) but they all lacked in some way (Jack really pissed me off ) and caused a blockage to my creativity. Apart from that, of all the 3 main platforms I stick to the Mac most of the time because a) it's unix and therefore secure and powerful (I can BASH, perl, python etc script) the interface (and keyboard shortcuts) is consistent across all software, i.e. it behaves in the same way, whatever you are doing, which I find is important for workflow. That's one of the most audacious things I've seen man

No, I meant the OP of the question, not the thread. BTW - 'Real Men' use the OS that suits the particular task, without ignorance, prejudice or excessive consumption of kool-aid

Yeah, Im an RHCE, but I made an assumption that the OP was a windows user. I've seen malware which messes with the hosts file on win, so I don't assume that they edited it directly (or knowingly).

Er, just slightly off topic?

He could have a bad hosts file. Localhost must be defined in there.

Hey can you like, stop fixing it every day, you're making the rest of us look bad

You are both attached to the same server? You won't see each other until you are a certain amount of KMs off the ground, and then you are added to the 'universe'. Its called the bubble. Edit:Crossover post

Thanks, I didn't realise I didn't need the dev build. I'll give it a try and report back :-)

Thanks, that explains the identical crashes after symlinking the lib. For now, I won't bother pursuing sqlite on the mac, I'll wait until the next server release. Until then, I'll continue to test KMP/sqlite/mysql on the Pi, to see if it can be stable, and how many clients it will handle.

I've tested further using sqlite on the Pi, and have no crashing issues so far. I've copied the db from the mac which was crashing when trying to dock in LKO, and on the Pi it doesn't crash at all, I can dock successfully. On the mac, I've also tried linking to the native sqllib (/usr/lib/libsqlite3.dylib) but the crash still happens when I get close (~20m) to the other craft. Here's a stacktrace if anyone is interested: at <unknown> <0xffffffff> at (wrapper managed-to-native) System.Data.SQLite.UnsafeNativeMethods.sqlite3_prepare_v2 (intptr,intptr,int,intptr&,intptr&) <0xffffffff> at System.Data.SQLite.SQLite3.Prepare (System.Data.SQLite.SQLiteConnection,string,System.Data.SQLite.SQLiteStatement,uint,string&) <0x003f3> at System.Data.SQLite.SQLiteCommand.BuildNextCommand () <0x001eb> at System.Data.SQLite.SQLiteCommand.GetStatement (int) <0x0006b> at (wrapper remoting-invoke-with-check) System.Data.SQLite.SQLiteCommand.GetStatement (int) <0xffffffff> at System.Data.SQLite.SQLiteDataReader.NextResult () <0x0031f> at System.Data.SQLite.SQLiteDataReader..ctor (System.Data.SQLite.SQLiteCommand,System.Data.CommandBehavior) <0x00177> at (wrapper remoting-invoke-with-check) System.Data.SQLite.SQLiteDataReader..ctor (System.Data.SQLite.SQLiteCommand,System.Data.CommandBehavior) <0xffffffff> at System.Data.SQLite.SQLiteCommand.ExecuteReader (System.Data.CommandBehavior) <0x00047> at System.Data.SQLite.SQLiteCommand.ExecuteNonQuery () <0x00027> at KMPServer.Server.storeVesselUpdate (byte[],KMPServer.Client,System.Guid,double,bool) <0x001da> at KMPServer.Server.sendPluginUpdateToAll (byte[],bool,KMPServer.Client) <0x027a3> at KMPServer.Server.HandlePluginUpdate (KMPServer.Client,KMPCommon/ClientMessageID,byte[]) <0x0003b> at KMPServer.Server.handleMessage (KMPServer.Client,KMPCommon/ClientMessageID,byte[]) <0x00147> at KMPServer.Server.handleConnections () <0x0015b> at System.Threading.Thread.StartInternal () <0x00057> at (wrapper runtime-invoke) object.runtime_invoke_void__this__ (object,intptr,intptr,intptr) <0xffffffff> I'm still experimenting with the Pi: a friend tried to join last night (Pi was using mySQL) and he had several connection fails before I decided to change the port forward to the mac server instead (we just wanted to play! ). However I'm going to try sqlite on the Pi when he has time to see if it reduces the CPU usage enough for a Raspberry Pi to be useful in this application. At the moment, with mySQL I don't think so but I'm not 100% certain.

Right. Although the mySQL process isn't using a huge amount of CPU (3-4% max) I'm wondering if I can get sqlite on the Pi and see if I experience the same issues as on my Mac (my mac is on 10.8.4 btw), and also see if mono reduces its cpu usage too...

Prior to the Pi, I was playing with the server on another Mac, using sqlite3 that comes installed in MacOSX. It seemed fine for a while but I had a problem with the server crashing because of sqllite - whenever I came within ~20m of another craft to dock. I could reproduce it every time. I installed mySQL and the problem went away.

I don't know, I haven't tested it properly yet. Edit: Initial sync for me takes most of the CPU, after that, usage drops to ~5% (the mono process). Other syncs (like when you come out of warp) raise the cpu usage to ~6-10%. That's just one player, still waiting for a friend to join up and test with me.

I just wanted to mention that I got KMP Server 0.1.5.1 working on a Raspberry Pi. Took a little bit of work to get mono and mysql running, but it seems quite stable and takes not too much CPU (not stress tested it yet). Thanks for the hard work on KMP :-)

Just wanted to say two things: 1) Thanks for this mod 2) What are .asciidoc files? That is a non-standard file extension AFAIK (I have used mac/lin/win on a daily basis for years), and KSP is a multi-platform game, so sticking to using well-established standards - .txt or .rtf would be more appropriate perhaps?

Any news on this, or maybe there's another tool that can be used instead?
