Summary:                    Deadlock
Description: 
We're seeing 1.4.20.1 deadlock periodically, but not permanently at first.
Most of the time the output of sip show peers or core show locks will not
return anything, then after a lengthy delay they will scroll across the
buffer.

call processing also stops completely during this time, then will resume.
after a few cycles the box stops responding in any meaningful way. output
of two core show locks captures attached.

Corydon76: I've been working with putnopvut on this, we can check that
version but this wasn't determined to be an actual deadlock, but a resource
starvation issue in certain situations related to manager connections.
