Reply With Quote #1

I'm encountering some errors that are crashing my counterstrike source linux server that's running metamod 1.7.1, sourcemod 1.2.1, and my custom sourcemod mod which includes an extension (.so) and a plugin. I'm running a Ubuntu 8.10 x64 server but using all 32-bit libraries for this server.

I'm really not sure what is causing these errors, be it the counterstrike code, the source engine code, metamod code, sourcemod code, or my mod code.

Here's the info I have on crash #1:

Code:

My guess is that this is a counterstrike bot related problem. My code doesn't really do much of anything with bots except treat them like any other player on the server, but since they're bots they're not really even using my mod the way players are. At first I thought this problem was related to bots not working on custom maps, but the bug appeared again after I removed the custom maps from the rotation/maplist. Has anyone seen this bug before, or know what I can do to fix it? [UPDATE] I noticed that a few people have had this bug happen on a purely CS:S server however no one said anything on how to fix it.

Bug #2

Code:
[Switching to Thread 0xf7da96b0 (LWP 32055)]
0xf6627f7d in CUtlLinkedList<NavLadderConnect, int>::RemoveAll () from /home/administrator/srcds_3/cstrike/bin/server_i486.so

Backtrace stopped: previous frame inner to this frame (corrupt stack?)
Sorry I don't have more info about this bug. Looks like the stack got corrupted or something. But I did notice that the server was in the process of changing maps when this happened.

GDB
I used GDB to get this crash info. I'm a GDB newb so if there's something I can do to generate more information which might help you guys help me fix these bugs or future bugs please give me some tips on how to get it. I know I should probably be looking at some memory but I suck at reading raw hex and also I don't really know how to find the memory that could possibly help me with these bugs. Any tips on using GDB would be greatly appreciated!! I'm currently just attaching to the process, setting logging to on, and then waiting for the server to crash, doing a backtrace and a core dump.

Any help on this stuff is greatly appreciated!

I'm experiencing some other crashes on the same CS: S server. If anyone has seen these crashes before, or knows anything about them, please reply!

Since the crashes are in Valve's code, you're not really going to get anywhere without digging through the assembly. Since these crashes are in strange places, I'd run your server without any addons and see if it still crashes.
