The high RAM utilization can case that. Please add more RAM. If you are using dual AV scann replace it with single and change to avira not Sophos . After changing restart the proxy from command line or if you don't how to do it reboot the computer. But most important , add RAM.
It does not change anything. When the ram is full it will happen. Add more ram if you can and fallow my instructions please , then inform here if it solved that for you.
Yes I did , but maybe it was already fixed but I am not sure , I will need to ask the support. Sophos AV use to spike RAM and SWAP. I am almost sure it was already fixed but worth a try to see if it helps.
I think it's fixed. My reason for using Avira is that I want a different AV at the periphery than is used on the internal devices. More and more of my customers are moving to Sophos AV with Endpoint Protection.
