hi,
i'm seeing an NPE in my broker, after which the broker is inoperable
without a restart. below is the amq related logging upto the first
occurence of the NPE. there's no obvious cause, and prior to the NPE
the broker had been working fine for 19 hours or so, logging pretty
much nothing, and had processed a few hundred thousand messages
ring any bells with anyone ?
thanks
craig
