CGI process is crashing twice a day and comes up after apache httpd process restart. I am running CentOS 6.3 Server , 16GB ram, i5 Quad core processor. With just only one wordpress blog running with site traffic around 40,000-50,000 impressions. During that time iam observing outage in my wordpress site. Here are my TOP command logs after and before restart showing PHP-CGI process comes to live after httpd restart.
