Tomcat dies suddenly

Question

Trying to diagnose some bizarre Tomcat (7.0.21) and/or JVM errors on a 64-bit linux (CentOS) machine.

I\'m load testing our server application and tried

Answer 1

If the JVM crashes, you should have a hs_err_pidNNN.log file; you don't have to do anything to enable this. Its location depends on your OS and how you are running Tomcat. On Windows, they can show up on your desktop, unless you are running as a service. Otherwise, they should be in the current working directory of the crashed process.

Your operating system probably provides additional tools for process monitoring; you could describe your environment more, or perhaps ask at serverfault.com.

It's also possible that jvisualvm is actually causing the crash.

I'd try reproducing the problem, and progressively simplify the scenario to help isolate the cause.
