I think I am just missing the Chinese fonts rpm. Is "taipeifonts-1.2-26.noarch.rpm" my only option? When I "ls" all the RPM's in the distro, and grep for "-i chinese," the only things that come up are: - kde-i18n-Chinese-3.3.1-2.1.noarch.rpm - kde-i18n-Chinese-Big5-3.3.1-2.1.noarch.rpm I did install "taipeifonts-1.2-26.noarch.rpm" (from the Redhat media), but I'm still not getting Chinese pages to look right. Did I choose the wrong font package, or maybe I have the wrong approach altogether? thanks, Mats Which would be seemingly KDE related. __________________________________________ Yahoo! DSL ?

But I needed 1 week to figure-it out ;) . Mine was to freeze every 1 hour.. At that time I had about 2 millions apache hits + mysql heavy. So I woke up (Nagios sent me an sms and rebooted server at nght) Due to this load decreases, I apply php eaccelerator and loade was steady to about 40.. Then I changed the kernel in grub.conf and everything went back to normal like a bad dream. Now that server has 3 millions hits per day and load is around 3, proc load between 20-40%. This bug is reproducible and I can prove with my cacti graphs. The difference between a bad kernel and a good one is on how much swap will show.. a bad one will never show more then 50 megs or so while a good one will cache almost everything.

I came to figure it was probably coldfusion because I saw there was some pretty major patches for it. But when I stopped coldfusion the cpu stayed pegged. Then I stopped apache and the cpu stayed pegged. Then I stopped networking and the cpu went down. I turned networking back on and it stayed low and has stayed low since. Not sure what that was all about but now it's working well. Thanks for your suggestions.
