I am seeing an issue with high cpu utilization at various times throughout the day resulting in user sessions timing out. When reviewing the output of "top" I see several httpd2-prefork processes running and some using up to as much as 70% of the CPU. This seems to only last for a couple of minutes and then things return to normal. This seems to happen at the start of class when students are logging in. Any suggestions are greatly appreciated. Attach is a screenshot of the top results. This this screen shot the Cpu around 50% but at times it is over 90%.
