Subject ActiveMQ takes a long, long time to restart as NT service
Date Wed, 03 Oct 2007 03:22:46 GMT

Hi there, 

I'm new to activeMQ 4.1.1 and trying to get it set up in our development
box, where it must run as an NT service.  I've used the TanukiSoftware
wrapper before, so I was familiar with the process and had no problems.  My
trouble started when I started trying to configure activeMQ security.  I
quickly discovered that many of the examples on configuring the
SimpleAuthorizationPlugin and so forth have some hidden gotchas.  So, I was
doing alot of changes to the conf/activemq.xml and restarting of the
service.  I finally found an example that I could get to work using the JAAS
plugin.  Hooray!  I then edited the config file again, because my goal was
to end up with three different users, each with three different roles: 
admins, producers, and consumers.   I added some stuff to the config file
and restarted but then noticed that I was unable to connect at all.  I
couldn't figure out what might have gone wrong, so I began commenting stuff
out of the config file to try to get back to my starting point.  However the
problem persisted. 

Eventually, I noticed that it was hanging on the line in the log that says: 
INFO  DefaultDatabaseLocker          - Attempting to acquire the exclusive
lock to become the Master broker

I researched this error on the net, but found nothing that helped so I gave
up for a while.  When I came back later to resume troubleshooting I then
noticed that everything was fine.  It apparently took about an hour or so
for whatever was preventing it from acquiring the exclusive lock to go away. 
I restarted again and noticed that the same problem occurred.   You can see
this clearly in the log below.   This time it took a couple of hours to
acquire the exclusive lock.

So, my only theory at this point is that the stop of the service is failing
to get rid of everything;  that something is hanging on through the restart
of the service that keeps it from acquiring the exclusive lock.  I've
studied the task manager trying to see what that could be, but it eludes me. 
There's no two occurences of the wrapper.exe or java.exe.  Not sure what it
could be.

Here's the wrapper.log:

And, here is the contents of my activemq.xml configuration file.  I should
be back at my original config file here with all the security stuff
commented out, but you can see where I was trying to go with this: 

<beans>
