Summary:                    LibPRI problem with restart of PBX processor
(Testing SVN 1688)
Description: 
Asterisk is connected to legacy Siemens PBX. PBX has dual CPU and switches
over active/passive processors at (or close to) 00:00.

During the switchover, the link stays up but the PBX sends SABME. Asterisk
should clear state to restart q921. A few seconds after the first call
comes in, we see the legacy PBX drops the link and tries to re-establish -
it normally does this after a protocol error (timer expiry etc).

I will try and reproduce with pri debugging enabled.

I do not see anything different in the PRI-Error-2010-05-25-14-30-2.txt
trace file that was in the PRI-Error-2010-05-25-16-31.txt trace file.

Maybe a trace file with libpri 1.4.10 during the swap would be
enlightening as to why it works and libpri 1.4.11.x does not.  Also is the
version really 1.4.10 or 1.4.10.2?

Also increasing N200 may help for 1.4.11.x to give the transition more
time to recover.
