Hi
I have this same error with CGP 6.2.5
I updated CGP 6.1.6 to 6.2.5 yesterday. It then had open files limit=256 !!!
Today I got back to 6.1.6 which has open files limit=119950 (without any Startup options).
I also tried with "ulimit -n 20000", but this doesn't work as these Log-Lines tell me:
CGP-Log:

17:27:04.302 2 SYSTEM open files limit=256

Looks like you've put "ulimit ..." instruction into teh SUPPLPARAMS line in Startup.sh. You should not. The file should contain something like
SUPPLPARAMS="any cgpro command-line parameters"
ulimit -n unlimited
"ulimit" is OS/shell command that changes the limits for the shell session later used to start he CGServer process, it's not a parameter fro the CGServer process itself.
It runs on an Xserve Quad-Core Xeon with Mac OS X 10.6.8
How can I solve this problem?

Betreff: too many files open
We see "too many files open" errors in our logs. And the server starts flaking out. We end up restarting CGP.

Looks like a lot of connections from the same address.
Running CGP 6.0.11 on Gentoo Linux
In the CGP startup script we have
ulimit -u 2048
ulimit -n 8192
10:42:19.4187 0 SYSTEM server 6.0.11 started under Linux(x86-64)
10:42:19.4187 2 SYSTEM start options: "--Base" "/var/CommuniGate" "--Daemon"
10:42:19.4187 2 SYSTEM open files limit=8192
10:42:19.4187 2 SYSTEM process core dump limit=0M
How do we mitigate this?
