For reasons I don't fully understand, load on the main web server and on the incoming mail servers (those which handle e-mail incoming from the net) is unusually high. I rebooted a file server used for both but it had no impact, I also rebooted the web server, and it didn't resolve the situation. On the web server, the hits aren't above normal, but for some reason a CGI program used by earthcng, livectr, and to a lesser degree a few CGI's used by others to distribute ads, seem to be waiting on disk I/O more than normal. On the mail server, the incoming volume is very heavy, way more than normal, and I'm not seeing any obvious loops or other problems. My spam load is also way above normal today. I don't know yet what is causing this. Full moon perhaps. I don't know. Seems like the spammers are extra busy but net activity in general is high for some reason.
