Last night, a server I run did something very strange: it swapped out
a bunch of pages when it apparently had lots of free memory. This
same server has had a more or less identical load for weeks and hasn't
swapped. Munin says:

When this happened, free memory was high. Any ideas?
This is a mainline kernel 3.0.19 with very minor and non-mm-related patches.
Thanks,
Andy
