Obviously the "parent"-JVM itself starts the other JVMs, so it must be
an application issue.
Do the "child-JVMs" stop when 21115 shuts down?
Do the child-JVMs terminate on "normal" signals like -SIGTERM?

I would try to log the exact time, when these additional JVM are being
started and compare these with things that were happening on the
"parent"-Tomcat - maybe you find a application dependency that way.

Just an idea: Maybe the parent-JVM gets a signal to restart itself that
isn't handled correct?
