ActiveMQ won't restart because KahaDB is locked

Turns out there were multiple AMQ servers in our QA environment. When I shutdown the first server, an exception was thrown for some reason and so it didn't release the lock. Possession of that lock then went to the other AMQ instance (the first server was the master, the 2nd server was the slave).

When I tried restarting the first server (the master), it wouldn't restart because the 2nd server had possession of the lock. I shutdown the 2nd server and the lock was released, allowing me to restart them both.

Check the data/ directory for logs.

And is this a typo? :8161.admin
Try :8161/admin
