Re: [Wrapper-user] java application is failing to start on HP-UX

[Tanuki S. S. <su...@ta...>]

Prasanna,
The SIGKILL that you saw in the log was sent by the Wrapper to
forcibly kill the the Java process after it did not shutdown within
the expected amount of time.  The question is where the SIGTERM that
initiated the Wrapper to start its shutdown came from.

Were you able to reproduce this problem?
