[Clusterusers] Re: cluster mailing lists & something funky on compute-1-3

[Wm. Josiah Erikson]

uh... that's clusterusers at lists.hampshire.edu obviously :)

compute-1-3 was stuck in permanent iowait with a breve process using up 
more RAM than the machine actually had (meaning it was in swap). I think 
it probably got stuck when the head node crashed and ended up with a 
stale file handle or something when the home directory got pulled out 
from under it.

I rebooted it :)
