GDB traceback

During cluster testing I found attached core file.
I hope you will know what to do with it.


How reproducible: Occasionally (probably on broker exit, while
the client was still running).

Steps to Reproduce:
1. Run two brokers in a cluster (but maybe this is not vital)
2. while qpid-perftest --base-name prvy; do :; done
3. Shut down the broker on which perftest is connected.
Actual results: Core is dumped.
Expected results: Connection should be closed cleanly on the client side.
  Without core file.

Additional info:
  Happened on mrg26.lab.bos.redhat.com
Comment 1 Kim van der Riet 2010-07-12 11:09:25 EDT
I am unable to reproduce this after many runs on mrg10. Could you give a little more information, please?

1. Were the brokers running on the same box as the client (perftest)?
2. How were the brokers started (ie what command-line options)?
3. How was the broker stopped? ie Ctl-C (SIGTERM) or kill/pkill -9 (SIGKILL)?
4. What is the timing between starting perftest and killing the broker?
Comment 2 Jan Sarenik 2010-07-19 10:07:14 EDT
Sorry, I was in a hurry that time and did not note the exact settings
into the description.

I was running the brokers with:
on mrg26: qpidd --known-hosts-url amqp:tcp:,rdma: --cluster-name=ahoj --cluster-url amqp:rdma: --tcp-nodelay
on mrg25: qpidd -m1 --port=12345 --cluster-name=ahoj --cluster-url amqp:rdma: --known-hosts-url amqp:tcp:,rdma: --tcp-nodelay

and killed the broker on mrg26 with CTRL-C. Perftest was running on mrg26.

The timing between starting perftest and killing the broker is the most
fuzzy thing here. I do not know and the core was emitted when I was not
focusing at that window with perftest so I found it just acccidentally
when switching among windows (in screen(1)).
Comment 3 Kim van der Riet 2010-08-30 14:16:05 EDT
I have not succeeded in reproducing this as yet; I suggest moving it out of 1.3.
Comment 5 Jan Sarenik 2010-09-16 09:16:59 EDT
As far as I remember, I was not able to reproduce it with later versions.
Yes please, I am moving it into 1.3.1 and will re-test later, then
probably close if it will not show up anymore.

I am closing this as NOTABUG.
