WRKJVMJOB gives three options for dumps (30, 31, 32) They probably want a Java dump (32) I haven't used the options before....but they are there

We've got an intermittent problem with a web app server running in
Tomcat on our V6 box, specifically with how it establishes a
communication link with another (ILE mixed-language) server on the same
box, and our developer on that project wants a thread dump.

How do I get this for him?

(FWIW, the handshake involves the ILE server sending an ASCII bell to
the requester [either the web app server or a desktop Java client], one
per second, until the requester responds [We call this the "ringing
phone" handshake protocol, and it's served us well for over a decade].
The web app server is intermittently failing to respond [leaving the ILE
server "ringing the phone" indefinitely], and according to the developer
on that project, the latest internal diagnostics indicate that it opened
the socket, but never received any bells.)
