mass session dropping

[john]

I am getting reports of lockups as well. It seems to happen while kids
are using firefox. The only cure is a hard reboot since
ctrl+alt+backspace is broken in Edubuntu 7.04. We're loosing 6-8 at a
time.  The server has more than enough umph.

Linux is starting to get a reputation around the school as an unstable
OS, sadly.  LTSP 4.2 was a better user experience for sure.
