[BUG] Map with 3D triangles causes server to crash

Post by eyebo » 18 Jun 2020, 01:50

There's a Canyon map that was causing servers to crash.

So I checked it myself.

Here's the crashlog from the server:
LogCrash_005E6F47.txt
(27.36 KiB) Downloaded 25 times
Based on the crashlog, I removed the 3D triangles from the Intro MT.
That seemed to be the cause. After removing the 3D triangles, the map loaded without issues.

Here's the original map with 3D Triangles:
Gharial.Map.Gbx

And here's the updated map with 3D Triangles removed:
Gharial.Map.Gbx

Tested with the 2019-10-23_20_00 dedicated server.

I don't have any logs as it was on servers started with standard executables but i also had the issue with an up-to-date server for the CCP on TM². A map made in the TMAll TitlePack : CCP#03 - Frozen Brakes.

The crash occured first slightly after i added the map on the server. I never had this issue before. I saw a crash once when trying to load a map but not just by adding it. And after that the server would crash shortly after starting. I had to remove the map from the MatchSettings file.

I contacted eFFecT, co-author of the map and he also point me towards 3d triangles likely being the cause:
it is because of the 3d text probably in the intro
it caused some big issues in tm2020 as well
hasnt been fixed in tm2 I guess
I assume MP development is totally dead until severe security issue is found, so i guess this map just won't be playable on servers.

The problem with this issue is that many map authors do not know about it.

And many server owners don't know about it either.

And imagine... server owners will never know which new map will crash their server.

3D Triangles is a normal feature of the game, and it's causing servers to crash. In my opinion, this makes it a serious issue.

It's also an issue that was already fixed in TM2020. So a fix is known. It just needs to be applied to ManiaPlanet.

The crash at least when added with Pyplanet is only a few seconds after adding the map. So until you added several maps at the same time you should be able to know which one caused the issue as a server owner.

But i sure agree it could be nice to fix this especially since a fix was found in TM20².
