I am purchasing a billing/support system in PHP which required Zend Optimizer. I downloaded the the 2.6.2 package becuase that's what I needed for my PHP version. I followed the instructions, and accepted all defaults during installation. Everything went fine. Then my site wouldn't load. I'm guessing the httpd service wasn't loading properly due to the Zend installation. I let it sit for about 30 mins thinking maybe it was doing something. THen I started getting messages in SSH like this: Message from syslogd@server at Wed Oct 17 15:38:01 2007 ... server kernel: CPU0: Temperature above threshold Message from syslogd@server at Wed Oct 17 15:38:01 2007 ... server kernel: CPU0: Running in modulated clock mode I copied my backed PHP.ini file to my /etc direction, restarted httpd, and everything is fine now. My question is, what did I do wrong? During the Zend installation the paths seemed to be correct... Has anyone else installed Zend Optimizer sucessfully on Plesk 8.2 & CentOS? I used the Zend Optmizer Linux x86-i386 tar file. Thanks for any help in advance.
