Is the srcds_run marked executable? You shouldn't start the server with anything but srcds_run. Make sure you are supplying the "-game" tag properly.
I can't help any further without a console output of some sort or and explicit listing of commands used.
Ok so I have been in contact with my host.
"Seems the mod was built for a 32 OS and specifically Ubuntu. You may want to ask in that forum in regards to CentOS 64 bit. That's what we run"
./srcds_run -debug -game gesource -tickrate 66 +fps_max 600 -secure +alias sys_ticrate locked +alias max_fps locked +exec server.cfg +ip xxx.178.55.xx +port 27015 +maxplayers 16 +map ge_runway +alias malo_3
Auto detecting CPU
Using default binary: ./srcds_linux
Enabling debug mode
Server will auto-restart if there is a crash.
Running a benchmark to measure system clock frequency...
Finished RDTSC test. To prevent the startup delay from this benchmark, set the environment variable RDTSC_FREQUENCY to 3192.000000 on this system. This value is dependent upon the CPU clock speed and architecture and should be determined separately for each server. The use of this mechanism for timing can be disabled by setting RDTSC_FREQUENCY to 'disabled'.

Does this info help any?
