Following on from my last update.

Since providing you with the rough dates when mixmonitor would 'be ok' or
'be out of sync with garbage at the start of the callers channel', I've not
made any changes to my environment or asterisk upto the next time I tought
this might happen.

I have taken periodic svn asterisk trunk (currently at 319421), after
following the install, performed and shutdown/cold start and a test call to
see the state of the mixmonitor file.   Over the last few days the issue
has still be there.

At 17/05/2011 18:26 i had in incoming call which resulted in having the
issue;  this date/time of call is about 24.4 days since the problem started
to occur again.

At 18/04/2011 08:35, at my first chance this morning I performed a test
incoming call, and ' mixmonitor is now ok with no sync issues'. 

So yet again - somewhere between 24-25 days, the issue, for me, either
starts or stops.
