Hi Guys,

I am running a Left For Dead 1 Linux 64 bit server running Ubuntu 20.04 LTS and it keeps crashing with these exact same errors all the time and i have no clue as to what is causing them (All At Different Times)

Any help would be grateful.

Sorry to bump this, but does anyone have any ideas ?

Another 43 crashes with exactly the same signature.

0 engine.so!Sys_Error_Internal(bool, char const*, char*) + 0xf2

Viewing raw the last thing mentioned is "l4d_Chat.smx" and "Removing Overide for Client Louis" while in yellow at the top it says "IVP Failed at /home/buildbot/buildslave/l4d_rel_linux/build/src/ivp/ivp_physics/../ivp_utility/ivu_vhash.cxx 157"

Could try removing that plugin. If that doesn't fix it then I would recommend removing half of all plugins and testing, continue removing/restoring half until you find the culprit.

Removed that, and it still had issues.

I decided to remove Playerpanel as it also referred to that, and changed bebop for multislots. Lo and behold, it is not crashing, so i am going to assume that either bebop or the playerlist panel was causing the issue, but i will try to narrow it down and report here to what the exact plugin was that was causing the total crash.

I really need to learn sp as i think i would enjoy it, and be able to help others out like you guys do. (Any receommendations on where to start would be really appreciated !)

Good job! Usually best to remove half/restore half and repeat until you find the issue. Although I did spend months once doing this, but I wasn't playing on the server and only checking every few days or week.

See the TUT thread in my signature to get started on SP.

Ok. After testing and the issue stopping, it rears its ugly head again.

I removed every single plugin except for sourcemod, and still ths issue persisted.

I removed Sourcemod, and no more issues, so i decided to check the kernel log files, and this is right at every single crash.

Dec 11 00:41:14 www kernel: [3815497.622183] srcds_linux[359161]: segfault at 6e616c67 ip 00000000ef975cb5 sp 00000000ff907280 error 4 in sourcemod.2.l4d.so[ef8e1000+15e000]

So it would like sourcemod is not playing ball with L4D1

Anyone any ideas ? or should i report this as an issue.

Which SM version?

I would try with the latest stable of MM and SM instead of the dev builds.

Hi Silvers,

I had rolled it back to see if it had any impact. It was

sourcemod-1.11.0-git6891-linux
mmsource-1.11.0-git1102-linux

I have now updated the both of them to

sourcemod-1.11.0-git6924-linux
mmsource-1.11.0-git1148-linux

and i have stripped it back to only the plugins that came with sourcemod and only 1 server which is running the plugins and got rid of the other one.

I can make it crash by simply changing the map to Death Toll (1st Level) and then noclip to the end and then slay the bots and when it tries to change level down it goes.

The latest error since removing everything but the plugins that came with sourcemod is the following, and they are all the same.

Code:
and the kernel dump error is

This error is linked to sourcemod, and causing a segmentation fault somewhere in the engine. and they only occur when sourcemod is actually installed, and there are no crashes when it is not installed.
