asterisk users - Dec 2003 - Asterisk freezes, no manager traffic, console functions

I have asterisk running as a voicemail system off of our Merlin Legend
switch.  We replaced our old Audix Voice Power (when the power supply fan
died and burned it up) with asterisk a week ago.  Many thanks to those who
provided information about integrated VMI on the legend.

The Audix system would, after a mailbox was closed, wait a few seconds,
then use that line to dial the switch and update the MWI status.  I have
asterisk mimicking this behavior with a script that watches the manager
port for the MessageWaiting information and then issues the same MWI
update call.

The Audix also used to refresh MWI status when the line was idle for long
periods of time.  I replicated this behavior by a perl script that gets a
list of all of the extensions on the Legend, and then one-by-one updates
their MWI status.  If I leave this script running (calls take 2 seconds
each, then a 30 second interval between mailboxes), eventually, asterisk
will freeze - a little.

An open connection to the manager port shows that manager information
stops flowing.  'show channels' in the CLI will show that one port (of
the
group used for the MWI updates) is left in 'Dialing'.  For asterisk to
respond to any telephony events, it must be stopped and started (though
'stop now' from the CLI does do the job).

Any suggestions as to where I might look to find the problem?
