ActiveMQ 5.1.0 queue SawTooth pattern

I am run ActiveMQ 5.1.0 moving roughly 120 messages per second into one queue
and then filtering and copying to 4 unique queues using camel where similar
consumers are consuming those messages. 

Over a period of time the memory trend starts to grow and we have learned
that around a certain point we need to go in and restart amq (maybe a
different conversation) when we do this restart and about 30% of the time
one of the unique queues will go into a sawtooth pattern where messages
don't get delivered until the peak we have seen this between 20k and 240k at
the top and then they get consumed. 

Have others ran into this issue, is it a known defect that I can't find, or
the bigger question does anyone know how to fix?

Thanks,

Curtis

Dejan,

Thanks for you reply yes we have spent time testing 5.3.x, 5.4, and now
5.4.2 with 5.4.2 being what we believe has been the more stable release
since 5.1.0. So far this appears to only happen in production and I don't
have a repeatable test case for this pattern, wish I did. Does that mean
that similar issues have not been seen before? 

Regards,

Curtis

Hi Curtis,

did you test some of the later versions? It be good if you could test a
current snapshot and produce a test case if the problem still exists.
