Please check your cat /etc/ambari-server/conf/log4j.properties file to find out the correct path for your log files.

@Sankar T

The best place to start is the ambari-server logs. These can usually be found on:

/var/log/ambari-server/ambari-server.log

Try to look at these logs (commands cat,less,more,etc) around the time that your ambari-server is going down to find more details

@Sankar T

Those are stack advisor error/messages. do you see stack trace in ambari-server log? usually stack advisor runs on config change and advise - some times that operation may fail.

@Sankar T stack advisor error should not bring down the cluster. check ambari-server.out log to see any errors

Ambari is not writting any log information. even ambari-server.out is also not having error log for that period.
