Frequent CTDs (mainly on scene change)

[baldamundo]

Been getting these a lot recently. 95% of the time they happen on scene-change. They're a lot like out of RAM crashes, but mostly seem to be happening at only ~3.2gb or so.

I think these have only been happening since I installed FAR, although it's possible there were one or two other smaller mods I installed at around the same time. I'm running a lot of mods, so likely it's some sort of conflict, but I don't really know where to start. Will try disabling FAR and seeing if that makes any difference, but given how widely used FAR is, it seems unlikely to be the culprit presumably ?

Mod list is here according to AVC anyway, although I feel like that might be a conservative estimate.

I've had a look at the logs, but I've not seen much that's meaningful to me. The toolbar errors (or some of them anyway) are because I set toolbar-settings.dat to read-only to stop it resetting, but I'd done that before the CTDs started happening.

I'd really appreciate it if anyone more knowledgeable with time to kill could just have a quick scan of the logs and let me know if there are any obvious smoking guns https://www.dropbox.com/sh/xl7jmwy3hvnt0iq/AACGzECS5Iedsso-BIoqdTHQa?dl=0

Thanks!

Okay, I can confirm it definitely doesn't seem to be FAR doing it.

Well, your first exception is with KOS:

kOS: Exception Loading TelnetMainServer.xml (maybe the first time you ran and its not there yet): Object reference not set to an instance of an object

So you might want to look at that first, then look at Mechjeb:

MechJeb module MechJebModuleWaypointWindow threw an exception in OnLoad: System.NullReferenceException: Object reference not set to an instance of an object

It did this quite a few times, then smartparts:

Then your drag cubes broke:

Then Tantares:

UnityException: Texture 'Tantares/Agencies/Tantares' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings.

Then the roster:

Then contractconfigurator:

So I think you're going to have to try the steps here, find which find which addons or combination of addons is causing this, and note down your exact reproduction steps for a consistent crash, ie: exactly what you click, which order, how many times you have to revert to the editor, what other programs you have running and your memory levels.

Sorry I can't be of any real help on this one.

Well, your first exception is with KOS:

That message is harmless. The settings it talks about are actually stored in the config.xml file, though, so the message needs to be corrected. There is no such thing as the TelnetMainServer.xml file.

But it's definitely not going to cause any sort of crash. When it can't find the setting it just assumes you've never caused that popup question to appear yet (the warning that you're about to activate a telnet server, and the warning if you take it off of loopback mode) and it presumes the default setting of "do remind me next time" for both of those popups.

[baldamundo]

Thanks. The odd thing is, though, I've only been getting these crashes recently but I've had most of the mods you mention installed for ages. Tantares was more recent though, so I guess I ought to start by testing that.

Btw, is it significant that these crashes always seem to occur when I'm at about 3.2-3.3gb of RAM usage?

[baldamundo]

Because the crashes seem to happen most frequently on my busier saves and and when I'm using larger vessels, but disabling a whole bunch of mods breaks most of my saves and most of my craft files, this becomes extremely frustrating to debug. Even doing a binary search is actually quite tricky like this
