Oracle Database - Enterprise Edition - Version 10.1.0.2 to 11.1.0.7 [Release 10.1 to 11.1]

SYMPTOMS

crs_stat -t  returns

CRS-0184: Cannot communicate with the CRS daemon.

CAUSE

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