Summary:                    Deadlock is happended.( between channel and sip_pvt
lock)
Description: 
I have been testing asterisk. (Trunk version)
When testing more than 4cps asterisk does not work.

I am confirmed reason for using GDB.
The reason is estimated to deadlock. Help needed.

Between thread ID 24 and thread ID 5 the circular Deadlock occurs.
Thread 24 (Thread 0x8cc8b90 (LWP 1886)):   chan lock(waiting) <-
sip_pvt_lock(acquired) <- monlock(acquired) 
Thread 5 (Thread 0x648ab90 (LWP 1948)): sip_pvt lock(waiting) <- chan
lock(acquired) 

Here is the debugging information.

What kind of hardware are you running this on and which Linux distribution
are you using?

Also, are you able to reproduce this consistently?
