   Code Block
   ps -efaux | grep --max-count 1 "cloudgateway" [c]loudgateway.pid | awk '{ print $2 }'

2. Capture the thread dump using jstack by running this command using the PID determined at step 1

   Code Block
   jstack PID > thread_dump.out

3. If the above command does not capture anything, try running this:

   Code Block
   jstack -F PID > thread_dump.out
