Version: 2.6.26-2
Severity: normal
I run a standard amd64 kernel in a core 2 duo machine under heavy network
traffic, and I keep getting tons of these (more than 28 in less that 2 days)
the last few weeks, regardless of all reboots:

This is simply the result of running low on memory, and almost certainly
*not* a bug. So the way to fix it is to install more RAM, or to stop or
limit some memory-hungry programs.
