Subject [jira] Issue Comment Edited: (AMQCPP-199) Segmentation fault at decaf/net/SocketInputStream.cpp (line 108)

Albert, Timothy

It blocked again, even with a server restart every 50 loops - it completed the cycle twice
and went stranded around loop 39.

I'm looking forward to close this issue as its subject wasn't reproduced after the changes
made during the past weeks, but the point is that I cannot keep the stress test for too long
(less than a couple of hours).

What I've also noticed is that it seems to block at the same test (test_openwire_async), so
I'm giving it another try without it, like we did with the CMSTemplate.

Anyway, it would be ok to me to close this thread if you agree that the log files attached
have little or nothing to do with the original segmentation fault that opened this issue.

>         Environment: RHEL 5.2 (32 bits), apr-1.3.3, apr-util-1.3.4, ActiveMQ 5.1, gcc

> 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!
