Im having high loads issues on one server. It works well most of time but then I get high load for 3 minutes and after that everything is back to normal. It happens daily which is unacceptable and I cant find out what is causing it as there is 100 sites on the server. top and show processlist at mysql results are the same as always, the same goes for io usage.
Any help would be appreciated? This is driving me crazy for days already.
eaccelerator causes hgih load at peak times. We are running php as fcgi, with eaccelerator, ioncube, zend optimizer and suhosin and we had to disable eacc in order to get the load back to normal. php version is 5.2.16
