Summary:                    IMAP crash multiple callers / callers hangup at beep
Description: 
A multiple CPU machine + asterisk-1.4.22 + imap2004g, with more than one
user in voicemail (not the same mailbox) disconnecting right after or close
to beep + 3 seconds timeout for abandon causes, is a bad combination.  

In same cases IMAP warnings about parsing response and in most cases a
segfault. I'd like to know what the root cause is and what fixes it? I can
produce any backtraces / scenarios anyone needs to lend a hand here.

---------------------------------------------------------------------- 
There is no hammer.sh script per say. Used custom PJSUA client that
connects, plays 30 second message, and hangs up. Would get 5-10 of these
working on leaving a message, givem them the 3-4 seconds to get past the
too short message, and SIHUP them.

Do not want to send that code because it will digress in to PJSUA not
being used correctly, SIP dialog not ending correct, etc. For those already
thinking that now this problem happens on a production system where PJSUA
is not even involed. PJSUA simply recreates call volume in voicemail for
me. It is not a PJSUA SIP usage issue.
