[resolved]Srcds hangs on startup

[Darkfoxx]

Server OS: CentOS 6.2 (64bit)
Processor: 2x Quad Core Xeons @ 1.86GHz (L5320)
Ram: 16 GB
Game(s): Team Fortress 2
Start Up Command: ./srcds_run -console -game tf +map cp_dustbowl +maxplayers 24 -autoupdate +ip 209.50.226.21 -port 27015 -tickrate 66
Admin Mods: SourceMod, MM:S

Srcds hangs after:

Code:

Network: IP 209.50.226.21, mode MP, dedicated Yes, ports 27015 SV / 27005 CL
SOLID_VPHYSICS static prop with no vphysics model! (models/props_foliage/grass_02_cluster01.mdl)

A strace on the process reveals this:

Code:

mprotect(0xa8e9000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC) = -1 EACCES (Permission denied)
mprotect(0xa8e9000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC) = -1 EACCES (Permission denied)
mprotect(0xa8e9000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC) = -1 EACCES (Permission denied)
mprotect(0xa8e9000, 8192, PROT_READ|PROT_WRITE|PROT_EXEC) = -1 EACCES (Permission denied)
...etc....never ends

From what I've read, mprotect sets protection on a region of memory. Why would permission be denied? Or if you have any other ideas, let me know.

So this was really odd.

Apparently this was caused by Metamod or Sourcemod. I moved my addons directory out of the way and TF2 starts up without issue. I'm going to further diagnose the issue, but it is resolved for now.

Edit: Narrowed it down to Sourcemod.
Edit2: Narrowed it down to a specific plugin.
Edit3: Final edit, I promise! This was all caused by SELinux. Apparently it was enabled by default on a fresh CentOS 6 install. I disabled it and MM:S and SM run without issue.
