If you log into the admin console at:

Then you should see a shutdown button.  The default admin id/password
is admin/password.

I agree.  Which message store were you using?  The default
`jdbm2_store`? JDBM2 has a nice Apache friendly license but much less
robust than the BDB implementation.  I'd recommend that you switch to
BDB as soon as possible.   Hopefully we can find a better embedded
database to use as a default which can also be re-distributed by
Apache.  For more info see:

I'd love to hear more about it.  Message size, destination type, # of
consumers, etc.
