I've been noticing that every day between 11 AM and 1 PM, the xdelta3.exe process pops up and hogs over 50% of the server CPU, severly slowing the whole network down. I believe that our Symantec Endpoint Protection 12.1.671.4971 is updating the definitions and maybe pushing them to all the network clients. This seriously affects our ability to work as our ERP solution (database in the server) becomes non-responsive and we can't take care of our customers.
Our server is an HP Proliant ML370 G5 (Intel Xeon CPU @ 2.33 GHz with 2 GB RAM) and runs Windows Server 2003 R2 (version 5.2.3790, SP2). All clients are Windows XP Professional SP3. This happens each and every day. LiveUpdate Windows Scheduling is set to daily at 3:30 AM.
I don't know why is SEP doing this but it must stop as we're headed into busy season and we cannot place our customers on hold for a long time while we restart all clients and the server to get the system responsive again.
I'd appreciate if someone could provide some insight / suggestions as to how to fix this situation.
Thanks!
