When troubleshooting various problems on the Content Gateway one might need to capture a Java thread dump. This KB article explains how to do that using jstack. If you do not have jstack installed, then you should be able to install it on CentOS 7 via the epel repo with: yum install java-latest-openjdk-devel -y
Instructions
Find out the PID of the Content Gateway process by running this command
ps aux | grep [c]loudgateway.pid | awk '{ print $2 }'Capture the thread dump using jstack by running this command using the PID determined at step 1
jstack PID > thread_dump.out
If the above command does not capture anything, try running this:
jstack -F PID > thread_dump.out
