Okay... My server is a P4 2.4GHZ, and has 2GIG of ram. Running Plesk 6 and RH9. For some reason, starting around December of last year, my machine started slowing down around 5-7 days into its uptime. Everything would start slow down, web, webmail, etc... rebooting always fixed it for another 5-7 days. Restarting processes like apache, mysql, mail, never did much to resolve it. It would fix it for 5 minutes and sometimes up to 24 hours, then it would just hang again. Rebooting always fixed it for another 5-7 days. So, I added another gig of ram to bring it up to 2 GIG. The server had a noticable increase in overall perfmance of server sites that ran vbulletin... php/mysql. Ever since the upgrade... although the serving of web pages never seems to degrade... about the 13th day... webmail access slows down... pages load slower... but on the 15th day, it becomes unbearable. Mind you normal IMAP clients work fine, vbulletin pages fly like the wind... usage does stay steady (via uptime) at around 3.00 - 5.00... which is much higher than normal, it increases it's avg over the days. I don't know what to do. Any ideas?
