Summary:                    Asterisk deadlocks with no errors
Description: 
Hi,

we have every https://issues.asterisk.org/view.php?id=5#c1-2 weeks a deadlock. 
Max 10 cc. About 40 users.
Never get any error message or warning.

Last time it happend 2010-12-21 (with version 1.6.2.13) the console
outputs some sip destroying packets and the peers go offline about 5
minutes later availible again and so on.. the asterisk didnt answered to
the sip packets or answered after a few seconds.

This time it happened (1 hour ago) (with version 1.6.2.15) there are no
such errors .. only nothing :)

When i wrote "sip show peers" it showed me the peers
but console dial 50 at context did nothing.

There is a fix for issue 0018310 in the pipeline for 1.6.2.17 which may be
relevant to one of both of our problems wufan.  

Are you using a lot of BLFs in your installation?  We have most incoming
calls go to a pool of three phones in the reception/admin area and almost
every phone in the place has those three monitored on a BLF.  The upshot is
that there are a lot of SIP NOTIFYs (maybe 40-50 or so) each time a call
comes in or when the call is answered.

I've go not evidence, but it looks like an invitation to exercise a race
condition to me.
