I had faced this error message
[ CSSD]2012-01-12 15:24:19.352 [1199618400] >TRACE: clssnmWaitThread: thrd(2), timeout(1000), wakeonpost(0)
[ CSSD]2012-01-12 15:24:19.353 [1220598112] >ERROR: ###################################
[ CSSD]2012-01-12 15:24:19.353 [1220598112] >ERROR: clssscExit: CSSD aborting from thread clssnmRcfgMgrThread
[ CSSD]2012-01-12 15:24:19.353 [1220598112] >ERROR: ###################################
First of all location of log file is $CRS_HOME/log//cssd/
and file name is ocssd.log
There could be many reason for this error but in a nutshell CSSD has killed the local host connection to rest of RAC cluster. In this case, you will notice a hint on a line above ERROR which says that timeout is happening. Further investigating the log files I noticed that heartbeat between nodes is not fast enough.
When I checked interface used by interconnect then noticed that it is running on slow speed.
By Changing speed of network interface resolve this problem.
