Summary:                    Asterisk suddenly slows down, and eats 100% cpu
Description: 
I'm running 1.4.10 (with reverted res_features from
http://bugs.digium.com/view.php?id=10415). Approximately
once or twice per week (restarted daily) asterisk suddenly starts acting
slowly, and eats 100% cpu. Call volume drops as it takes really long time
for customers to get to agents, but this doesn't improve situation in any
way.

Last week i recompiled with DONT_OPTIMIZE, DEBUG_THREADS and DEBUG_LOCKS,
so now i can attach debug output.

I killed asterisk with "killall -5 asterisk", so that core is dumped.

Attached files:
backtrace.txt - backtraces taken from core

report.txt - various information ("top", "core show threads", "core show
locks", "core show channels") right before i killed asterisk.

normal.txt - top, and channel count when under normal load (30 minutes
after kill)

cli.txt - multiple consecutive executions of "core show threads" and "core
show locks", when problem raised.

Ok, almost a month, and no such problems so far. Can you close the issue
