Unmatched acknowledge with storm and activemq

["S. M. Allman" <sc...@gmail.com>]

I have two questions.

Recently our normally healthy storm system has been stalling. Looking in
the activeMQ logs we see an exception which begins with this message :


2014-03-05 13:21:05,626 | WARN | Async error occurred:

 Has anyone seen this problem before, and if so, how was it remedied?


 Second, is this the correct forum to pose this sort of question? If so,
does there exist a handy tool for searching by keywords through the mail
archives?


 Thanks in advance,
