When I first setup Q-S and Sophos I also setup an automated virus
definitions update script that would pull down the latest definitions from
Sophos whenever a new alert was sent out by Sophos.  The idea being that my
virus defs would be updated within a few minutes of Sophos alerting me of
any changes.  This sounds like a good, smart thing to do....Until a posting
a few days ago from our very own Jason Haar.

Jason, you briefly alluded to how you perform updates. If I recall correctly
you don't do them immediately but wait until late at night and down load the
vdefs once/day.  You also said that during the updating one must be careful
as it could screw up message scanning if a message was being scanned while
the vdefs were being updated.  Did I understand this properly?  If so, would
this scenario hold true if you used Sophie daemon (which I do) instead of
sweep (the commandline executable)?  Doesn't sophie load all of the vdefs
into memory and won't re-read the vdefs unless it is HUP'ed?  If this is
true then one could update the vdefs at any time, HUP sophie so that any new
messages get scanned with the new vdefs, and old sophie child processes
still scanning messages would still be using the old vdefs and not be
affected.  Of course if I still used sweep then what you have described
would be true.  If the problem does occur that you described what sort of
error messages does Q-S report?

Am I on base or in left center field? It is early morning but I have had my
tea and a good nights sleep so my brain is probably functioning as good as
can be :-)

Ed.
