connect: No buffer space available

First time I’ve gotten this problem when trying to ping another host:

$ ping pong
connect: No buffer space available

The command ifconfig didn’t show anything unusual, but dmesg showed some interesting lines:

[332083.737268] ipv4: Neighbour table overflow.
[332205.552806] net_ratelimit: 15 callbacks suppressed

I noticed that minidlna sucked up 100% from one core, but I don’t know if this is related. I restarted minidlna and the network, and all was back to normal again:

$ sudo /etc/init.d/minidlna restart
$ sudo /etc/init.d/networking restart

When I was back online again, I was curious and googled the problem. I found some hints to check the routing table and arp table, which I’ll do in the future should the problem ever arise again.

My platform for reference:

  • Distribution: Kubuntu-11.10 Oneiric Ocelot
  • Kernel: Linux narcissus 3.0.0-13-generic-pae #22-Ubuntu SMP Wed Nov 2 15:17:35 UTC 2011 i686 athlon i386 GNU/Linux
