--------------------------------------

             Summary: crash in pn_transport_set_max_frame
                 Key: PROTON-566
                 URL: https://issues.apache.org/jira/browse/PROTON-566
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: 0.7
         Environment: 3 boxes.  1 with senders, 1 with receivers, and 1 in the middle with
a single router.
            Reporter: michael goulish


Here's what I do:

( I have saved all relevant software so I can repro this. )

  1. On router box, start 1 router.
  2. On receiver box, start 1000 receivers.  With delays in between each group of 50, so as
to avoid backlog problem.
  3. After receivers are all started, start 1000 senders also with delays.
     Senders start up but do not yet begin sending until I manually "signal" them by touching
a file.
  4. Short time after sender start sending, qdrouter crashes in proton code, with this traceback:

  Core was generated by `/home/mick/dispatch/build/router/qdrouterd --config ./config_1/X.conf'.
  Program terminated with signal 11, Segmentation fault.
