VMG8823-B50B freezes after 40-60 days in bridge mode

Hi,

I'm using two VMG8823-B50B with the latest firmware 5.13(ABEJ.5)C0 in their easiest mode: Just as a bridge (modem) for SVDSL lines.

Unfortunately the devices freezes after around 40-60 days in operation. In this state, it seems the LAN ports are software wise not working: The bridge mode mostly stops (so WAN goes down on my pfSense router), the VMG can't be accessed via Telnet, Web or SSH. The LEDs are working normally (so I think the hardware NICs are still fine).

That looks for me like a serious software bug, especially as no watchdog etc. restarts the VMG. They are also no accessible for a remote restart, so this is a very bad situation.

Others are reporting the same issue.

Is there any known firmware version without this issue? Older ones (but with the same modem code), or newer beta versions?

Thanks!
