> My last question is I had 79 Mb in free memory plus ~476 Mb in swap space. I wondering why PF as the last resource doesn't use swap memory to load the tables.

Kernel memory, including that allocated by pf, will not get swapped out. We
wouldn't want to have to wait to process a packet until we'd read the relevant
pf table back from swap space.
