Our CGP 5.0.2 system just went down.  Linux Mandrake 2.6.15 kernel, Intel 32-bit.  Running on the Reiser filesystem.  It came back up Ok with a manual restart.
 
The following was in the syslog:
 
Feb  7 11:32:09 iowa CommuniGatePro: failed to write seqID
Feb  7 11:32:21 iowa CommuniGatePro: CommuniGate Pro Server 5.0.2 finished

Extracting what seems relevant from the CGP log...a few seconds prior to the crash, I see some failure to create temp files, then:
 
11:32:09.05 0 TEMPFILE(363779999) failed to create the file Queue/09/363779999.tmp. Error Code=too many files open in this process

Is this something we're supposed to configure in Linux, or what are reasonable limits?  Resource limits?
 
We compile our own kernels, so is there a place we should be configuring the number of open files?
