[Freeswitch-users] Sofia freezing for 5 minutes then starting again

[Tim St. Pierre]

Hi Steven,

Thanks for the suggestions.  I'm hoping once I get the upgrade done it will all go away. 
I have watched it happen at least once.  I was on the phone at the time.  Console activity 
more or less stopped, except for a few calls hanging up.  The console remains responsive, 
and my call wasn't dropped for at least a minute or two (media timeout?).  I was able to 
run sofia status and other commands that use the database, so I'm assuming that the 
connection was still working.  All our media is runs through the box, so I think things 
are fine on the Ethernet level.  I do see higher load averages - maybe 3-4, but that's the 
only obvious indication.  It's not taking CPU beyond 10% or so.

We are using MySQL as the core DB and also as the DB backend for each sofia profile.  This 
is connecting through ODBC of course.

If I can get the other kinks worked out, then I will try 1.2 stable in production and 
we'll see how it goes.

-Tim
