Dave,

Is there any way to verify this?  Vmstat perhaps.

This morning I caught my FC2T2 machine before is lost connectivity with
the outside world (ssh worked).  Local X and VT access were gone. 
Vmstat at the time indicated ~3300 free (K bytes?) on a 512MB machine. 
Last night before I left it was around 339000.  /proc/meminfo seems to
coincide, but not top.
