If the JVM is crashing frequently, what steps would you take to diagnose the issue?

Question

Accepted Answer

To diagnose frequent JVM crashes, follow these steps

Check JVM logs for any error or exception messages
Analyze system logs for any hardware or operating system issues
Review any recent changes or updates to the JVM or application
Monitor system resources like CPU, memory, and disk usage
Use JVM diagnostic tools like Java Flight Recorder or VisualVM
Consider analyzing heap dumps or thread dumps for memory or concurrency issues

Accepted Answer

We need to take several iteration, at least 7 iteration, of thread dump for the JVM process id and then we will analyse the thread dump and try to find out the faulty thread. If thread dumps did not get clear picture then we need to take Heap Dump and analyse the same.
