Game crash when switching from game to vab/sph or when attempting a docking maneuver

After a few quick tests on my part this issue seems to be specific to my save file. When I create a new game, I can rapidly go from game to/fom van to/from game to/from sph. So that being said:

Steps that lead to event that causes the game to crash:

1. Load game, enter VAB/SPH (doesn't matter which)

2. Load vehicle into game (adjusting craft or not)

3. Launch vehicle (or not)

4. Return to VAB/SPH

5. Crash to desktop, 'send to apple' report generated

I'd also note that for step 2, if I do make changes to the craft, the things I changed do not persist when I relaunch the game, as if the game didn't bother saving the craft changes (this doesn't happen 100% of the time and I haven't seen a pattern. Could be a feature that I'm just not understanding). I'm wondering if this might have something to do with the crashes, that the game is expecting a part to be on the ship but it isn't there.

Steps that lead to event that causes game to freeze (no crash report generated, KSP.log doesn't look odd to me but it's not like I really know, it does say something about not bothering to save debris right before freeze.)

1. Load game, enter VAB/SPH (doesn't matter which)

2. Load vehicle into game (adjusting craft or not)

3. Launch craft

4. Rendezvous another craft in orbit

5. Approach target to dock

In this case, again it will just freeze and i'm forced to command-tab to desktop and force quit.

One of these two events happens for every flight, every time. Now, as I said, this seems to only affect one particular save file from some quick tests, so it's not game breaking in a literal sense. But, this could be my second persistence file loss since I bought the game (first time was a drive wipe :( ) so i'd rather try to avoid that.

Plugins:

1. BoulderCo CityLights/Clouds

2. Environmental Enhancements

3. MechJeb2

4. ModuleManager 2.5.0

5. NavyFish DockingPortAlignment

6. ProceduralFairings

7. SCANSat

8. TachFuelBalancer

9. TriggerTech Kerbal Alarm Clock.

hey thanks!

Hey, thanks Master Tao.

I figured out the docking port freeze, that was the DockingPortAlignment mod. I'll look into that later but before then I want to figure out what is causing the program to crash when switching to VAB. Actually, it's not just to VAB but any scene change is at a high risk of crashing. I'm at the point where I now expect a crash after every other scene change. I've also noted that the game sometimes freezes at an auto-save point, but for now i'll assume that's a separate issue.

About my setup:

I'm on a Mac book pro 2012 (last model before retina), latest OS X, 8GB ram, and an SSD (which is new, issues were occurring at the same frequency on my old disk drive). As far as mono:

As far as plugins, I've added the ActiveTextureManagement in hopes that would help manage memory but that didn't seem to do the trick (at first it seemed to help a bit).

That is an out-of-memory issue:

KSP(6262,0xa0efa1d4) malloc: *** mach_vm_map(size=4198400) failed (error code=3)

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

Receiving unhandled NULL exception

I highly recommend Active Texture Management to solve the problem. You'll probably want the aggressive version.

Thanks!

I forgot to mention but at some point I did install Active Texture Management to try to solve this; the non-aggressive version.

So based on your input, I uninstalled the the regular version and installed the aggressive version. I also installed the DDSLoader because I read that might help with performance. These two steps helped reduce crashing but it does still occur. I guess at this point I'll start stripping out mods one at a time. I did add HotRockets and SmokeScreen since I started this thread so those will go first.

thanks.

With all due respect, ATM does not solve the problem. The problem is that KSP does not handle an out-of-memory condition gracefully, it simply sails obliviously into a beachball freeze with no warning of any kind. ATM helps, by increasing play time until it happens, or allowing you to add more mods, but the root cause still exists. The root cause is that KSP does not have sufficient error handling for out-of-memory conditions.

Most of the discussions of this issue that I've seen lead to a chorus of "you're running mods, it's the mods' fault". But Squad prominently uses KSP's support of mods as a selling point, to the extent of linking to "Mods @ Curse" on their website and even having "Modding Mondays" on their blog. They can't have it both ways - if they're going to tout mods so highly, they need to be able to handle the basic underlying housekeeping. The responsibility for memory management cannot and should not fall upon the shoulders of mod creators, it needs to be handled by the core software. Squad cannot of course control how many plugins you drop into your gamedata folder, but they should handle errors more gracefully than simply letting the program freeze and make the user force-quit. The analogy I like to use is elevators. Otis can't stop you from trying to fit 30 sumo wrestlers into one of their elevator cars, but they have a warning to let you know when it's overloaded. They don't let the car move at all, as opposed to letting you take your chances and just drop into the basement on a broken cable.
