    su: cannot set user id: Resource temporarily unavailable

      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 18352 0 65 12:58 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d
      grid 15880 4370 18378 0 65 12:59 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d
      grid 15880 4370 18408 0 65 13:00 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d
      grid 15880 4370 18514 0 65 13:01 ? 00:00:00 /u01/app/11.2.0/grid/opmn/bin/ons -d
      grid 15880 4370 18530 0 65 13:02 ? 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.
