Hey Yoav,
when you say 'sockets remain bound', do you mean the hexadecimal addresses?
how should I check these sockets?
Also, does anyone know a good CPU usage monitor for linux?
Cheers

I mean the network sockets: use the netstat command to see if tomcat is
still listening on ports (8005, 8080 by default).

Well, Catalina did it again, suspended this weekend.
But following Yoav's recommendation I ran './catalina.sh stop' and then
did a 'kill -s SIGQUIT' on the JVM process and got this lovely long
thread dump in my catalina.out.

The only thread that makes any sense to me, because it refers to a bit
of my own code, is thread number 15. I use my bean to download
selected
files from one of several ftp mirrors.
Is it a daemon thread?
If you could post just the few lines of each thread in your dump (no
need for the
By address I assume you mean the hexademical numbers in the square
brackets on the first line of each?
15 is a daemon, I've posted a few lines from each:

Yes.

I don't have a good idea. It's strange they're all daemons. Does the
CPU usage go way up when the JVM process is hung? Do the sockets remain
bound?

Hey,
Catalina.sh shutdown connects to the shutdown port (8005 by default) and
tells the server to shut down. Tomcat shuts down all its parts, and
that includes destroying servlets, filters, listeners as mandated by the
servlet specification. But tomcat does not call, for example,
System.exit(),
Howdy,
So basically, I iknow this is off-topic for a tomcat-users page, but if
I wanted to track down all the threads that are opened within the JVM
at
any one time, and the nature of the threads (ie Daemon etc.) and where
they come from etc. can I do this?
Sure. If you send a SIGQUIT to the

Howdy,
My first problem is the definition of the JVM, i cant find it as a
process in its own right, I can only find the process for catalina,
sending a SIGQUIT to:
/usr/local/j2sdk_nb/j2sdk1.4.2/bin/java
-Djava.endorsed.dirs=/usr/local/tomcat/common/endorsed -classpath

Howdy,
If I shut down Catalina and the process persists, then can I assume
that
all the Catalina-associated threads have been shut down and what I'm
looking at are the persistent threads?
Yeah, plus the JVM root threads (main, Finalizer, Event) that cannot
shut down before your threads do.
Howdy,
I was under the impression that the start script first checks for
another Tomcat instance, and bails if it finds one. Is that not true?
That's basically false. The startup code will try to bind to the ports
specified in server.xml. If they're taken (by any program, tomcat or
other),
I have Catalina Tomcat 4.1.24 connected via jk2 to Httpd 2.0.47 on RH9.
It seems every now and then, tomat just simply hangs. When I try to
shutdown the Catalina process via catalina.sh, it doesnt remove the
process?! So I have to 'kill -15' it, then start up catalina again.
I get very little
the original process is still runnning.
Has this happened to anyone else?

Howdy,
However, I have come to realise that on occaison, the 'stop' command
does not work, and when I restart, I thereafter create two copies of
the
original tomcat. this should not be possible because the first tomcat
should be using the same port, and thus blocking the restart, but
somehow,
Fantastic...
but i dont quite get it, here's the command from catalina.sh:
exec $_RUNJDB $JAVA_OPTS $CATALINA_OPTS \
-Djava.endorsed.dirs=$JAVA_ENDORSED_DIRS -classpath $CLASSPATH \
-sourcepath
$CATALINA_HOME/../../jakarta-tomcat-4.0/catalina/src/share \
-Djava.security.manager \
Howdy,
so thought it's cut off, the process is exactly what catalina.sh
started, so why doesnt catalina.sh stop it?
