connect: No buffer space available

[breorg]

Hi,
Im remotely managing a Ubuntu LTs 6.06 Lamp Server which is being used as a content filtering system (Squid, Dansguardian and basic IPTables Only)

My clients are experiencing slow Internet responce times, when i log into the server and try to ping Local IP Addresses i recieve the following error

connect: No buffer space available

Any Ideas?

Thanks,

Im guessing the lack of responces is due to not enough information.

This firewall was not setup by me, but has been running fine.

Router 10.0.0.138

Looking at other google hits. Try not using network-manager. Also, may have info entered incorrectly, check that. Also driver incorrectly installed. Screw this, google this:

ifconfig no buffer space

Plenty of hits. Repost with more info
