Definitely an option. I could blast the server with ap every 10 minutes. But it's not too elegant in that not all apache children are guaranteed to serve requests, so some will stay in swap. I've been doing a bit more testing actually, and I have to be honest with you here. I'm assuming the httpd processes are in swap, because according to the ps docs, processes surrounded by [square brackets] are swapped out. But I think ps might be lying because as soon as I start apache, the processes appear as [httpd], and even if I blast the server, they stay []'d. Here's what I'm seeing: root 29307 0.0 3.4 24028 17332 ? S 10:51 0:01 /usr/local/apache/bin/httpd nobody 29309 0.0 3.7 25212 18724 ? S 10:51 0:00 [httpd] nobody 29310 0.0 3.9 27260 20228 ?
