Hmm,
what do you mean exactly. 
The first backtrace is with a version without DEBUG_THREAD build.
This shows same behavior but not the message about the frames in local channel.

The second coredump is a DEBUG_THREAD build. This one shows the message and comes back to normal state sometimes, but mostly crashes.

> We have 3 Asterisk server (a,b and c)
> we have also 3 different user (Caller, Chef, Sek) .
> User Caller on Server a
> User Chef on Server b
> User Sek on Server c
> Now Caller Dials to Chef
> Chef has a call rule via agi to only accept direct calls from Sek, all other calls are transferred to Sek.
> So the call from Caller on server a is tranfered to Sek on server c automatically
> Sek accepts the calls
> Now Sek will do a unattended transfer of caller to Chef
> Now the server b with Chef shows no action on the dialplan anymore and blocks
> Sometimes also crashes.
