RE: Tomcat's Shutdown.sh doesn't. At least not reliably. (7.0.25) -- Anybody know how to get a thread dump of a job?

Tomcat won't shut down while there are non-daemon threads running. Make sure all the threads you start are daemon threads or monitor the shutdown and end them. Be especially careful of JDBC connections. Make sure the connections are closed.

Subject: Tomcat's Shutdown.sh doesn't. At least not reliably. (7.0.25) -- Anybody know how to get a thread dump of a job?

About an hour ago, I posed this question to the Tomcat list (at apache.org):

Running Tomcat on various AS/400s (V6R1 or later OS), we've found that
shutdown.sh doesn't reliably shut down the server, and we frequently
have to shut it down forcibly (i.e., finding CATALINA on a WRKACTJOB,
and giving it a "4" with "OPTION(*IMMED)").

Port 8009 does appear to be open before we call shutdown.sh, and it
does appear to be closed after we call it.

Or where I should look for indications of what it could be?

On the Tomcat list, Chuck Caldarale suggested:

Can you take a thread dump of the Tomcat process after shutdown.sh has
been used?
http://wiki.apache.org/tomcat/HowTo#How_do_I_obtain_a_thread_dump_of_m
y_running_webapp_.3F

Unfortunately, the link he gave me doesn't say anything about how to get a thread dump on an AS/400.
