Hi Charith,
can you confirm which release version of the Java Broker you are using
(it's always worth trying the latest version - in this case I'd grab
the latest 0.16 RC that Justin posted a couple of days ago - though
I'm not aware of any bugs that would cause this error)?
It would also help if you could send full broker log files that are
generated when this occurs - the best way is to raise a JIRA and
attach the log file there (stripped of any confidential information it
might contain - obviously).
Cheers,
Rob
