SEP12.1 RU2 Network Communication fail during definition update.
We have around 4000 SEP 12.1.2015 clients. From that number around 1000 are "Toolcontrollers"
We are in te process of updating from SEP11 client on 1000 computers and we start to have some issues when the new definitions are dowloaded. Some of our client-server application loose some heartbeats and disconnect. We mostly got 2 disconnection one at the start of the definition update and one at the end.
We currently enable only the realscan and antivirus components but we installed the firewall component but it is disabled for the moment.(No policies, everything is off)
We never got any disconnection whit SEP11 but we got some about 4 days/week with SEP12 on specifed client.
Is their something that has change? Is there something that i can tweek to minimize the impact or do I need to completly remove the firewall component?
BTW no IPS is installed
