Heap Dump not working Centos 7

I have added following setting in my catalina.sh file -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath="/root/logs".

But still the heap dump file is not created when tomcat is going down. I have this setup on centos 7 on AWS.

Please help me in solving this issue... Thanks in advance.

Solution

I would suggest try create it manually if it is not generating automatically by using a JDK bundled tool called jmap, although we recommend that you use the automatic method above for best result.

For Linux/Solaris-based Operating Systems: Please execute the following command on Linux OS:

$JAVA_HOME/bin/jmap -dump:format=b,file=heap.bin <pid>
