Juliano Carniel commented on AMQ-1927:
--------------------------------------

Hi Bruce, 

just for a feedback, the last (mis)information i gave is not real, it became to be a tomcat
NIO problem. I Have updated to 6.0.18 and the problem is solved. I haven't tried the the new
tomcat with the producerFlowControl turned on yet, but as soon as i try this i will reply
to this.
I think this could be a tomcat problem, seen that the report for this issue is with the tomcat.6.0.16
wich one i was using.

Thanks in advance.
