[cobalt-users] No load, all memory used after improper shutdown

["cbtrussell" <cbtrussell@xxxxxxxxxxx>]

Hi all,

Two of my RaQ4i's were unexpectedly cycled yesterday (power blink, bad UPS).
Neither were properly shut down, both came back up immediately. Now they
both are using swap memory, though neither has any load whatsoever. Here's
the top output from one, a 4i with 512MB:

I've sorted the output by memory so no need to show the balance. For
reference this is what I normally get after a clean reboot:

Any idea what the deal is? MRTG shows (obviously) swap being allocated after
the reboot on both machines, but before this event neither had even come
close to showing all the physical RAM used.

The archives suggest that there's no way to remedy the situation without
another reboot. While nothing's "wrong" per se, I'm not comfortable with
things not being "normal".

Thanks for your comments.
