error sending response: not enough free resources

[meeinter]

All,

I get many errors in my logs similar to the following. These errors
coincide with the computer losing all network connectivity. They
usually happen when the network connection is under some load

You didn't say which NIC you are using.

Please post the entire output of dmesg.
In addition, posting the output of ifconfig -a may also be useful.
