Database problems

Some combination of Serendipity, PHP, Apache, and Postgresql are causing intermittent lockups. I am working on trying to figure it out, but I'm not really sure what is going on. If you don't see this message, just be patient. :)

I am working on a Theological post, and I am hopeful that I can get it done by tonight, but if this server won't get quiet, who knows....

UPDATE: That was productive... I've had to roll back almost every change I made to the server to find the problems, since it just made regular use worse. That said, I know archives and Categories were bad mojo, so I've disabled those plugins until I can do some more work on figuring out what's wrong. Of course, I probably won't be able to find it when I look....

Update 2: Server guys everywhere: always run xntpd with the -x option. My new Server's clock wanders badly, so I have to syncronize it with the atomic clocks. Without the aforementioned -x option, the system clock would occasionally go backwards, and databases just plain hate that (as in I'm lucky that locking up is all it did). Maybe this is it.
