Crashing after a couple of scene changes

[Tonas1997]

I'm playing KSP 1.8.1 with a relatively large modpack and, as stated in the title, the game crashes after a couple of scene changes. My modlist is as follows:

Note: the above list doesn't include RealExoplanets and RealExpansion, which I sinced removed to test for the culprit.

Most of the crashes I've had seem to point out a method located in scatterer.ScattererCelestialBodiesManager.findCelestialBodies(), which then calls a default Unity method called UnityEngine.Object.FindObjectsOfType(). Now, I posted this issue to the mod's GitHub page and, as I ended up agreeing with, the author said this problem was impossible to solve for the time being, as the memory access violation occured deep within the Unity engine internals. Memory usage on all those crashes was at about 75~80% of the total, which is not unusual for my regular playsessions.

So, in any case, this is really a matter of speculation. Could the problem be caused by a broken planet pack - either Real Exoplanets or Real Expansion? High memory usage that increases the likelihood of threads stomping on eachother's feet? Some obscure issue with Kopernicus? The crashes aren't exactly deterministic, so I'm inclined to believe in something related to memory management. I run the game on a laptop with 16 Gb of RAM.

I am running across the same problem with scatterer.

 

 

  

Scatterer unfortunately still crashes the game for me after scene changes, despite running v.0.0610 (as seen below in KSP.log).

[LOG 19:14:26.849] [AddonLoader]: Instantiating addon 'Scatterer' from assembly 'scatterer'
[LOG 19:14:26.851] [Scatterer][Debug] Core instance created

[LOG 19:14:26.851] [AddonLoader]: Instantiating addon 'ShaderProperties' from assembly 'scatterer'

It runs just fine for about an hour and then crashes upon scene change.

The last line in KSP.log before the crash is:

[LOG 20:48:17.846] [AddonLoader]: Instantiating addon 'Scatterer' from assembly 'scatterer'

 

And in my error log it says:

I am running KSP 1.9.1, with about 200 mods installed through CKAN (all the most common ones). 

Although while quite a few mods are the same, there are also many differences between our mod-lists. But as written above, it seems to be related to scatterer causing an access violation.

I am not sure whether that is down to some mod conflicting with scatterer or whether it is scatterer running into memory problems.

[FasterThanFlourite]

After removing some of the mods, I have now about 20 less and the crashes seem to have gone away.

Likely it was caused by an incompatible mod. Probably one of these:

• AtmosphereAutopilot
• CommNet Constellation
• CommNet Manager
• CommNet Relays
• Contract Pack: Giving Aircraft a Purpose
• Contract Pack: Kerbal Academy
• Decal Stickers
• Double Tap Brakes
• Engine Lighting
• Engineering Roles - Final Frontier Ribbon Pack
• EVA Handrails Continued
• Firespitter Resources config
• Hangar Extender
• KSP Rank Ribbons - Final Frontier Add-On
• Lithobrake Exploration Technologies
• Near Future Propulsion Extras: Hydrogen NTR Configs
• NEBULA Decals Continued
• Operations Roles - Final Frontier Ribbon Pack
• Persistent Thrust
• QuickBrake
• QuickContracts
• QuickHide
• QuickMute
• RasterPropMonitor
• RasterPropMonitor Core
• RLA Stockalike
• Science Roles - Final Frontier Ribbon Pack
• Smart Parts
• STM's Expedition Ribbons - Final Frontier Ribbon Pack
• Surface Experiment Pack
