Pete,
I would take some of the options out:
-make your queue size 100MB
-reboot the machine.
If not successful then start eliminating sites your feeding, pqact,
pqbinstats, etc. If you are still having problems running bare bones let
me know. Also, has anything changed recently with the machine? New OS,
patches, etc.. We are running Irix 6.5 with no problems. In fact thelma
is SGI with 6.5
