A couple of days ago I had a spate of these in the router log..

Feb 8 20:32:27 kern warn kernel: nf_conntrack: nf conntrack table, drop=6492, ct.count=22028 clean cnt=13

This is typical of quite a few entries, and I've not seen them before. Are they some sort of data clearing process?

It means the iptable is full, this normally happens when to many concurrent connections are used eg torrent like connections.
