Subject [jira] Commented: (AMQCPP-199) Segmentation fault at decaf/net/SocketInputStream.cpp (line 108)
Date Mon, 17 Nov 2008 07:35:32 GMT

    [ https://issues.apache.org/activemq/browse/AMQCPP-199?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=47434#action_47434
] 

Alexander Martens commented on AMQCPP-199:
------------------------------------------

After successfully running the first loop with its 100 passes, stopping and restarting the
server, it got locked during the second loop, at the 29th pass, inside test_sessions_with_message_listeners
(test_openwire_async.test_openwire_async).

I'm about to retry with 50 passes per loop tonight, as gdb shows nothing interesting (just
seems to be waiting for a message to come).

No segmentations faults though.

> We're getting occasional segmentation faults in our Python based application.
> The easiest way to reproduce it is by running pyactivemq's stress tests (src/tests/stresstest.py).
> The offending line seems to be always the same.
> I send you attached a full gdb postmortem back-trace.
> Any help will be appreciated!
