The conclusion took place in a different thread: Daniel committed a
patch to master on 2 July

http://lists.sip-router.org/pipermail/sr-dev/2010-July/008097.html

and asked people to test the patch on 5 July prior to backporting it
into 3.0:

Klaus Feichtinger took the time for validation, and things seem to be
looking good. However, AFAICS the patch wasn't brought into 3.0 which
means that you still run on a race-conditioned version of SIP-Router
that causes the log message to appear quite frequently yet.

Daniel, considering Klaus' successful test runs would it be acceptable
to get the patch (commit f1c35c1325) into 3.0 from your point of view?

It definitely doesn't cause any critical issues to the proper working of
SIP-Router. The worst it can do is mess up a call's dialog state when
the race condition kicks in. Once the race condition is ruled out,
occurrences of the message boil down to broken UAs as Henning pointed
out already.


HTH,
