edCore.dll Crash - b2DynamicTree::RemoveLeaf + 0xBB


Recommended Posts

Hi, 

We've been having these crashes recently on Kola, random, reported by multiple clients in multiplayer. We're still uncertain if it's caused by the Kola map or DCS core itself. Can you please investigate?

Thank you.

I'm seeing exactly the same type of  errors, happens to me when I launch the game from the UI launcher, crashes when selecting launch game.  If I disable the UI launcher the problem appears to go away, this is 100% reproducible for me.

I'm sorry, but this is a completely different error you'rer eferring to in `KERNELBASE.dll`, ours happen while flying and in MP, please create a different forum post for it to avoid confusion. Thank you.

Hi, 

We've been having these crashes recently on Kola, random, reported by multiple clients in multiplayer. We're still uncertain if it's caused by the Kola map or DCS core itself. Can you please investigate?

Thank you.

@shaji I saw this crash (repeated) on a dedicated server running the MarianasWW2 map, reported it, and it hasn't happened again recently. Just speculation, but I think that some updates to the Essex carrier, including specifying it's draft (which was missing), may have been the fix in our case. It's hard to know as it isn't spelled out in the patch notes every time that update x fixes crash y. It might be worth looking at any ships in your mission, their waypoints, and the sea depth in those areas for some sort of clue as to what might be causing the crash.

Good luck.

I'm sorry, but this is a completely different error you'rer eferring to in `KERNELBASE.dll`, ours happen while flying and in MP, please create a different forum post for it to avoid confusion. Thank you.

Nah, shaji is right, yours looks more like an issue with the Visual C++ Runtime. There was an update to DCS recently that required a reboot, did you do the restart? If yes, then you should probably re-install the latest VCRuntime from Microsoft https://aka.ms/vs/17/release/vc_redist.x64.exe
If that doesn't fix it, it could be related to the sqlite3 db that the launcher uses, probably for some localisation strings or something. But one step at a time. Of course just running DCS without the launcher is also an option, I do that.

Hi all, we do have a report open internally and we are looking into it. 

thank you 

Are you talking about my issue or the original subject issue, or are the root causes the same...?  If not I'll raise a separate issue.
