Environment

VMware Smart Assurance - SMARTS

Resolution

To gather jstack information invoke the below command:
./jstack -l <ESM_Server_PID> > jstack_output
 
In the case where ESM server is not responding or hung, jstack can be invoked with the following command:
./jstack -F -l <ESM_Server_PID> > jstack_output
 
When jstack command is not on your machine, do the following:
Download the non rpm form of JDK, i.e.  jdk-XXXX-linux-x64.tar.gz and extract in to a directory (This will not be an installation. From the extracted directory, jstack can be invoked)
