Purpose
When crsd.bin fails to start, resource ora.crsd status from "crsctl stat res -t -init" does not show ONLINE, and "crsctl check crs" may report "CRS-4535: Cannot communicate with Cluster Ready Services".
Common cause of crsd.bin start up failure is in <note 1050908.1> - "Case 4: CRSD.BIN does not start". This note provides further steps to troubleshoot as in some cases crsd.bin dumps with no clear reason which makes it difficult to identify the cause. For example, from $GRID_HOME/log/<nodename>/crsd/crsd.log:
2011-05-11 10:54:17.636: [ AGFW][11828] Initializing the resource ora.<RAC>.db 1 1 for type ora.database.type

By reading the log, it's unclear why crsd.bin fails to come up. The cause is <bug 10638125> (duplicates: <bug 14769944> <bug 11925853>), it happens as OS user "oracle" is removed.
