Hi
I have a 2820Vn running 3.3.5.2 Beta_0414 / r26876 (and was running Firmware 3.3.4.1 with similar symptoms).

1 ADSL2+ and 1 Cable modem/ethernet linked line.

What happens is every 2-3 days, I start dropping packets on the WAN side (both ADSL and ethernet) in a total intermittent way . Bad enought to prevent VPN connections to be stable.

I first thought it was one DSL link , but failing over to the cable modem/ethernet link during the outage doesnt resolve the issue.

I havent got any firewall features/QOS turned on the, and I dont recall any similar issues before upgrading to 4.4.1.

Only way to fix the issue is to reboot, and then the modem stays stable for 2-3 days.

Looks to me like a memory leak, which is quite upsetting when you know the pric for these routers.

Any takers?
