oracle 19976 19950 0 Apr10 ? 00:06:47 /home/oracle/oracle/product/10.2.0/crs/bin/ocssd.bin

root 19323 1 0 Apr10 ?

00:08:47 /home/oracle/oracle/product/10.2.0/crs/bin/crsd.bin

CAUSE

This is caused by a cron job that cleans up the /tmp directory which also removes the Oracle socket files in /tmp/.oracle

SOLUTION

Do not remove /tmp/.oracle or /var/tmp/.oracle or its files while Oracle Clusterware is up.
