We've installed Tomcat 7.0.64 on an ec2 without using the tomcat ami ie do it yourself.
It runs fine however for no apparent reason, tomcat occasionally gracefully shuts down for no apparent reason. The instance continues running, just tomcat stops and the last few lines in the logs suggest it has been commanded to do so.

We start/stop using service tomcat start service tomcat stop ie via the init script, which for example runs /bin/su tomcat $CATALINA_HOME/bin/startup.sh
Any ideas why this might happen in AWS?
