Comment 32 for bug 1152736

Nope, I'm not using LVM snapshots. I'm thinking it's something to do with embeds or media objects - further attempting to work today showed that whenever the flashplugin was loaded (in either firefox or chrome, showing a video in a page) it would swap to death until those processes were killed.

I'm doing more testing/tweaking myself, things like disabling SDD deadline in rc.local to see if that has any effect.
