nf_conntrack: table full

[billion_fan]

Hi All

I'm seeing a bunch of these in the system log-
kern warn kernel: nf_conntrack: table full, dropping packet.

From what I've been able to find it could be torrents from an internal machine or a DDOS from outside? Is there some way maybe via the shell to get more info in what is actually causing these log entries? We've updated our router to a 8700NEXLR2 as the previous 7800VDOX was having intermittent WiFi issues, but did see similar entries on the 7800 as well.

Cheers
Peter

It will be hard to comment as we have never sold the 8700NEXLR2 within the UK

Hi There

It's not much different to a 7800 or 7800VDOX. No VOIP and menus pretty much the same. Can telnet and get into busybox etc but wondering if there is a way to dig deeper to see what is causing the issue?

The only way to find out which device is causing the issue, is to disconnect devices one by one, until the logs the disappear.

Once you have pin pointed the device, you can then reboot the router, and leave the device disconnected, to see if the logs appear again.
