Hi,

nproc kernel parameters is fully utilized. Find out the utilization of nproc by

#sar -v 1 11

See the column proc-sz

xxx/yyy

Here xxx is the current valu and yyy is the maximum value.

If fully utilized you need to increase it.

HTH,
Devender

1) Just for grins check /etc/rc.config.d/netconf and make sure there is no conflict between current values and what you tried to add.

2) netstat -in

3) I agree with the assessment that this box has a lot of processes on it. It does however not seem to be doing an awful lot of paging. Memory use itself is not high.

ps -ef | wc -l

How many proceses actually running.

kmtune | grep maxuprc

Is the maximum number of processes for a given user, the root user being exceeded.

vmstat 10
