Summary:                    Asterisk crashes or locks up when leaving imap
messages
Description: 
While leaving voicemail messages over imap, i would occasionally see cases
where all asterisk would stop responding to sip signaling and a "sip show
peers" shows no entries.  I am able to reproduce this problem 100% of the
time by using a simulator (sipp) to send calls with media to an extension. 
I am allowing 2 simultaneous calls at a time, and the message duration of
the voicemail is approx 30 secs.  Using this method, the problem always
occurs within the 1st minute or so.  I see errors in the asterisk console
before the problem occurs.

I am using the Maildir format on my imap server, so each message is left
in a separate file.  My imap server is dovecot-1.0.7-2.el5 running on
rhel5.1.

My sipp options are:
sipp -sf uac_with_media_30secs.xml -s 650xxxxxxx 192.168.196.40 -l 2 -m
1000

I was initially using asterisk 1.4.21.2 built from a tarball.  I also
tried building from an svn checkout of the 1.4 branch
(SVN-branch-1.4-r134976) and saw the same problem.

Most times asterisk locks up, however in one instance asterisk seemed to
crash.
I will attach the errors I saw in the asterisk console to this ticket.

I can reproduce this problem very easily, so just let me know what you
need from me and I can get it to you.

Best Regards,

Mike Oliveras
