asterisk users - Feb 2011 - Realtime and Local Channel Crash Problem 1.8.3-rc2

Hi,

I have been having a problem with asterisk crashing when using local channels
and realtime on asterisk 1.8.3-rc2.
The example given here is I think the easiest way to reproduce this problem.

In extensions.conf I have:

[internal]
switch => Realtime/extensions/p
exten => 301,1,Answer()
exten => 301,2,Dial(Local/501 at internal)
exten => 301,3,Hangup()
exten => 501,1,Answer()
exten => 501,2,Playback(demo-echotest)
exten => 501,3,Echo()
exten => 501,4,Hangup()

Where dialling 301 puts you through to 501 and you hear the echo test message
fine. However if I move 501 to the realtime database extensions table and remove
it from extensions.conf asterisk hangs on the local channel dial, then
completely dies a few minutes later (console stops responding to commands) with
killall -9 asterisk being the only way to stop it.

In both cases I can dial 501 directly with no problem.

The last message on the console (with verbose 10) -- Executing [300 at
internal:2] Dial("SIP/1014-00000001", "Local/501 at
internal")

Everything works fine with the exact same setup and asterisk 1.8.1.2.

Thanks,
Nic.

Nic,
  I can reproduce this using the latest SVN for the 1.8 branch.  I
don't get the console locking, but SIP definitely deadlocks every
time.  If you want to open a ticket, I'll upload the bt/threads/locks
info that I have.
