[Wrapper-user] wrapper process is hung

[Cade T. <ca...@ca...>]

Hello All,
I'm not sure how to figure this out so figured I would turn to the experts.


I documented everything here:

http://stackoverflow.com/questions/35283549/java-service-wrapper-parent-process-is-hung

But the simple summary is that when I issue a kill $pid (SIGTERM/15) on the
wrapper process (the JVM is long dead via something else killing it with
SIGKILL/9) nothing happens. (this is the same call from stopit() in the
wrapper.sh distributed by you all.

As documented in the other question, that causes other issues downstream
because without the wrapper dying correctling, I can't restart them both.

Any ideas on how to best trouble shoot this?  I'm not sure what would be
"stuck" in the wrapper C code so that a SIGTERM would not be properly
processed? SIGKILL/9 works as expected.

If this was a Java process, I'd get a thread dump and a heap dump, but not
sure how to attack this C code.  Maybe dig through something in /proc/$pid?

Any help is incredibly appreciated!
