Subject Re: activemq-admin failing on snapshot
Date Fri, 15 Aug 2008 12:07:41 GMT
You might want to capture a stack trace of the broker while it's
trying to initialize the jmx connector to get an idea which call is
the one that's blocking excessively.  Is your DNS resolving name
quickly on that machine?
