To many files open

[vvzar]

What can I do to resolve this errors? (Very quickly nonstop repeating at console screen.)
It happens after some normal uptime.

I set ulimit -n 4096, hope this help.

Use : java -Xms512M -Xmx1024M -jar nemisys.jar

Use : java -Xms512M -Xmx1024M -jar nemisys.jar
it doesnt help...
ulimit -n 4096 does not help too...

I have tried -xms2048 -xmx4096 - uptime increased up to 2 days, but after all I get same error.
Looks like somewhere file descriptors leak, or whatever

I do a daily restart of Nemisys with a log rotate, so the logfile never gets to big. I don't have such an issue.

by this action, you dont let nemisys to get to critical condition, but issue is out there :)
