Neighbour table overflow (No buffer space available)
Hello ng, ---
Recently our firewall (running debian woody testing) began having
difficulties on the outbound uplink, injecting lots of these errors into
the syslog:
Jul 7 22:43:30 localhost kernel: Neighbour table overflow.
It's quite serious, because at the same time, in timeslots of approx. a
minute I get these fallouts:
vladka:/var/log# ping www.uni-c.dk
connect: No buffer space available
The fallouts typically last 2-3 minutes, and as far as I can see they're
not exclusive, i.e. it can happen to one destination and not another.
Also, it doesn't seem to have anything to do with iptables.
I have no idea how to proceed. Could it be a hardware failure?
