[asterisk-users] crash

[Rilawich Ango]

Hi all,
  I have seen a lot of message talking about asterisk crashed when
using queue and mixmonitor together.  I do use both in our system and
also get the crash (segfault) randomly.  I don't know it is related to
the reason above as I have no idea about how it happened.  I get the
core dump below.  If anybody has any idea about the root cause of the
crash, please tell me.

Asterisk 1.4.13
Zaptel 1.4.5.1
Libpri 1.4.1
Addons 1.4.4
