Connection drops during AV pattern updates

Since when is this happening to you?

I believe we face a similar issue since 11.09.2020. It was working fine until that date.

Hello Gianni,

Thank you for contacting the Sophos Community!

How did you notice this happened when the AV updated, how were you able to correlate the AV updates with the traffic being dropped?

I am just trying to collect some info.

This might be related to an issue that is fixed in MR3 about failed pattern updates. 

Regards,

The time reported in the log for the update was the same time that the Anyconnect client on one of my machines reported disconecting on several consecutive days. I did not notice the issue today though so it might not end up being the cause. I will continue to monitor. 

Just happened again. The pattern updates don't fail, but traffic is being dropped when they are applied. Any insight on when MR3 will be released?

Hello Keith,

Thank you for the follow-up!

MR3 is coming out at the end of this week beginning of the next.

Can verify Mr3 does not solve this problem. As a work around we have to set to manual update (not ideal) or put to daily and reboot the router after hours, there is no way to set the schedule to a specific time. Otherwise, need to fix it to allow traffic when updating IPS/AV signatures.
