Summary:                    Asterisk randomly crashes when using chan_misdn
Description: 
We use Asterisk and mISDN in very utilized server in a callcenter. With
Asterisk 1.4.17 and mISDN 1.1.7.2 works everything fine. With Asterisk
1.4.21.2 and mISDN 1.1.8 Asterisk randomly crashes. We tried combinate
Asterisk versions 1.4.20 to 1.4.22 with mISDN 1.1.7.2 and 1.1.8 and the
result is the same - we did not found working combination. When I stop
placing calls to chan_misdn, Asterisk is stable.

Current configuration of the server:
Debian Etch with kernel 2.6.18
Asterisk 1.4.22
mISDN 1.1.7.2
Beronet ISDN card BN8S0

Complete trace log is in attached file. In trace are two crashes - at
09:39:55 and at 09:51:11.
