Summary:                    Heavy locking in manager.c results in eventual crash
and loss of CLI commands and intense CPU load
Description: 
We run some scripts connecting to Asterisk AMI to display realtime Asterisk
statistics.  When our AMI stuff is connected to Asterisk versions 1.4.25 to
1.4.30rc2 there is heavy duty locking and CPU load spiking which will
degrade voice quality, kill the Asterisk CLI commands like core show locks,
core show channels etc... and I have seen the load in HTOP reach 300 until
Asterisk is forcibly restarted. Asterisk 1.4.24 is not effected so we don't
think it is our scripts...

Core show locks and gdb asterisk --pid=`pidof asterisk` 'thread apply all
bt' is attached as txt files
