> I can reproduce the problem doing the following:
> - running stomp benchmark with the attached scenario
> - run check_stomp in a loop against the broker on stomp+ssl (check_stomp in this case
connect via ssl, drain the destination, send one message and check he receive that message
back)
> the check_stomp command line /path..to/check_stomp --config /path/to/file.conf --broker
stomp+ssl://host --destination /topic/test.stompssl
> to see what check_stomp does: http://svnweb.cern.ch/guest/MIG/trunk/mig-nagios-plugins/src/check_stomp
> This has as result:
> - very high cpu load remaining after stopping the tests, it remains high until you restart
the broker
> - apollo web console reporting some stomp+ssl connections open which are not appearing
in netstat at all
> I attach you a thread dump where I am sure that no clients could have been connected.
> nestat output for stomp+ssl port:
> tcp        0      0 0.0.0.0:61133               0.0.0.0:*                   LISTEN  
   25699/apollo
> The screenshot about the web console is attached also, it shows the connections remaining
in Apollo.
