debug onoutofmemory unable to start tomcat

I have the option to restart tomcat on outofmemory. 

-XX:OnOutOfMemoryError=/opt/tomcat/bin/restart.sh

Here is the restart.sh

#!/bin/bash

pkill -9 -f tomcat
/opt/tomcat/bin/startup.sh

Tomcat executes the script , kills the tomcat, but doesn't start it back again. Here is the log

java.lang.OutOfMemoryError: Java heap space
# -XX:OnOutOfMemoryError="/opt/tomcat/bin/restart.sh"
#   Executing /bin/sh -c "/opt/tomcat/bin/restart.sh"...

Please help me debug why tomcat doesn't restart.

Solution

  • I did'nt find an answer for this question, but I ended up running a health check on tomcat every 2 minutes which solved my problem of manually restarting tomcat whenever it is out of memory.
