Java process not respoding but resuming after I do a thread dump with jstack -F

I have an weird issue with a Java process which is stuck (once/twice per day) and it only recovers after I execute:

jstack -F ${PID}

While the Java process is stuck, If I try to do a thread dump with jcmd, I receive AttachNotSupportedException.

I only managed to do a thread dump using jstack -F, and using JDK version in sync with JRE version, JRE version that was used to start the java process.

The only thing I can think of, is that maybe the OS Scheduler does not allow CPU time for the Java process, and if I do a jstack -F I force it to allow it to run?

Any feedback will be appreciated.

Regards,

Cristi
