When I do rather large scans, nessus slowly starts to use more memory. Right
now I am scanning only 2 of my class B networks and am noticing heavy
paging. Usuall starts in the second half of the second class B.

Pulled that from top... I am doing a tcp ping of port 80 to see if the host
is up then checking for the ISAPI overflow and to see if it has the codered
backdoor in it. I would like to schedule a big scan of about 10 class B
networks but I am having perf problems. Anyone else see this?
