Database Software

This morning I was not able to login as grid.

I got a message su: cannot set user id: Resource temporarily unavailable

I checked the /etc/security/limits.conf
grid soft nproc 16384
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536

oracle soft nproc 16384
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536

I did a ps -eLf|grep grid|wc -l
18756

There was unusually lot of processes. I could see a lot of processes associated to ons.

grid 15880 4370 18059 0 65 12:56 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d
grid 15880 4370 18075 0 65 12:57 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d

grid 15880 4370 18807 0 65 13:03 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d
grid 15880 4370 18860 0 65 13:04 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d


I also did a cluvfy check to see if there are any issues.

Post-check for cluster services setup was successful.

I am wondering why the ons processes keep increasing.
