Author Too many open files - FileNotFoundException

Two new errors: Too many open files, and FileNotFoundException.

WAS6 sp.02. Running on SuSE Linux Enterprise Server v9 sp2.
Sample application "PlantsByWebSphere" still works, Admin console still
works.

Is there an WebSphere "application" specific configuration setting to
address this error?
See log snippet below.

Thanks so much! --Jim

Probably need to talk to your SysAdmins - this is an OS limit, not
something within WAS.

I am the SysAdmin of the Linux box. I did increase ulimit -n from 1024 to
10000, and am still seeing this message.

I'd believe it more of an OS problem if the sample application also stopped
working, but it keeps on working and the OS seems to be running fine.

Thanks,
Jim
