Subject [jira] Created: (AMQ-3055) in message exchange

                 Key: AMQ-3055
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.4.1
         Environment: Mac OS X 10.6.5.

The architecture: I have two twisted-python daemons, one writes job to query and subscribes
for an answer, the second does the job and replies back to the first via topic. I use stomp
for communication with activeMQ.
            Reporter: Pavel Shvedov

And after some load I get the exception in activemq log:

2010-11-26 14:07:09,653 | INFO  | Transport failed: |

Examples of load:

ab -n100000 -c1 http://host (always throws exception after about 16339 topic + queues
