Illegal Instruction

[GolemdX]

Server OS: Ubuntu Server 9.10
Ram: 0.25GB
Game(s): Counter-Strike Source
Start Up Command: ./srcds_run -console -game cstrike -port 27015 +ip 173.206.243.207 +map cs_office +maxplayers 2

I haven't gotten the server to run yet, so this is a fresh install. When I run the above command, I get 'Illegal Instruction' and the core gets dumped. This is what I see...

Code:

Auto detecting CPU
Using AMD Optimised binary.
Enabling debug mode
Server will auto-restart if there is a crash.
Illegal instruction (core dumped)
BFD: Warning: /root/srcds/core is truncated: expected core file size >= 1376256, found: 1064960.
email debug.log to linux@valvesoftware.com
Tue Jan  5 20:08:10 EST 2010: Server restart in 10 seconds

I'm not even sure about the processor so I don't even know if it is AMD. The debug.log says...

Code:

I haven't gotten it to run and I had to install gdb originally, but I have no idea why this error would happen.

EDIT: Would it make a problem because I installed it as root?

servers running as root should not crash. but you take a severe security risk if you do so.

if you want to find out what cpu you have, run:

Code:

cat /proc/cpuinfo

(and post the whole output here if you don't understand it)

Apparently it is an AMD processor.

Also, searching 'Warning: /root/srcds/core is truncated' on Google doesn't help much because the first listing is my topic. I'll try re-installing as a normal user and see if it helps...

I have seen related problems with old AMD's and linux, there is other "unsolved" threads about this.

I don't really understand this message, but it is not related to game servers. the "core" file is created by linux when a process crashes and will contain a snapshot of the processes memory etc. it can be used e.g. for debugging.

try loading it with gdb (the linux debugger), i.e.:

Code:

gdb /root/srcds/srcds_amd /root/srcds/core

then, at the gdb command prompt run the "backtrace" command and post the output here. "quit" will exit the debugger.

[GolemdX]

Well, there is no core after the process has been terminated, and I have to if I want to be able to enter more commands...
Running backtrace on srcds/srcds_amd comes up with 'No stack.'.
