Install Jstack On Ubuntu -

For quick debugging on a restricted server, kill -3 <PID> works without any JDK installed, but the output is less structured and may be redirected to logs.

This should output the version of Java installed on your system. install jstack on ubuntu

First, see if you already have a JDK installed by checking the version: javac -version Use code with caution. Copied to clipboard For quick debugging on a restricted server, kill

2345 com.example.MyApplication 1234 jcmd kill -3 &lt

for i in 1..5; do jstack -l 12345 > thread_dump_$(date +%H%M%S).txt sleep 5 done

If you have multiple JDK versions installed, you can switch the default:

grep -i deadlock deadlock_dump.txt
