Chris,
Thanks for the response. I went ahead and got the info you requested.

Some background info:

Tomcat Version: 5.5
JDK Version: 1.6.0
I've run into a very annoying problem while trying to enable
automatic context reload on our development server. It works well
when there is not a user logged on to the system (I guess that means
while there is session info on the server), but if someone is logged
in, then Tomcat fails to reload the context.
I can confirm that Tomcat 5.5.26 both reloads and stops properly when
multiple sessions are active. Persist-to-disk works as expected, and
sessions are retained across the restart/reload.
I suspect there is a problem with your specific webapp and/or setup.
My thoughts too, I'm just not sure where to look.
Another issue that may be related to this is that Tomcat will not
shutdown cleanly when someone is logged in (Tomcat hangs at "INFO:
Stopping service Catalina). Rather, we must close the console window
forcefully, then start the server back up to an error (IOException
while loading persisted sessions: java.io.EOFException)
That's interesting: your session (de)serialization is failing because
the file is incomplete. I suspect this is because the sessions are not
correctly written to the file before application stop. Perhaps session
serialization is the actual problem.
Can you attempt to shut down Tomcat and then check:
1. A few thread dumps
(http://wiki.apache.org/tomcat/HowTo#How_do_I_obtain_a_thread_dump_of_my_running_webapp_.3F)
I put them at the bottom of the message.
2. The CPU usage of your webapp and/or threads
The CPU usage jumped to about 05% right before it hung, and then fell to
00% and stayed there. Memory usage held steady at 37K.
I'm wondering if serialization is either running-away (infinite loop,
etc.) or stalling (waiting for access to a locked object) and it's never
completing.
Looks to me like it's waiting for a locked object, like you said, rather
than hitting an infinite loop.
I used jstack to get a stack trace on the Tomcat process when it hung
on context reload. I won't post the details unless someone thinks
they might be helpful (Don't want to fill the email with too much
stuff).
I think they might be. Go ahead and post the thread dump.
See the bottom of the message.
However, I know I read somewhere that Tomcat will hang on shutdown
if there is a non-daemon thread still running.
While this is true, it shouldn't block a webapp from reloading (it will
leave the old webapp in memory, so the old webapp won't really go away
completely, but the new webapp should load in its place and handle
requests).
jstack reports three non-daemon threads: main, VM Thread, and VM
Periodic Task Thread. I don't think that's causing the problem, but
figured I'd better let you know anyway.
Nope, those are normal.
Here are a couple of thread dumps of tomcat, the first taken about 5
seconds after the hang, and the second a couple of minutes later, while
still hung.
Note that in the main methods, there is one stack frame with some XX's
in it. I put those there to cover the name of a method which could
identify our company. Nothing personal, I'm just not allowed to let that
information leak out.
After seeing that stack frame, however, I looked into the method which
it referenced. It appears to be sending a HTTP POST message to a servlet
which we have running, which is supposed to log the user out when it
recieves said message. Could the problem be that the servlet is shut
down before the message reaches it?
