Weird error

[Fri Mar 21 21:10:59 2014] [alert] (4)Interrupted system call: FastCGI: the PM is shutting down, Apache seems to have disappeared - bye

Restarting Apache didn't fix this problem. I had to kill nginx and restart it.

I was getting the same error, it has to do with the Apache settings in /etc/httpd/conf.d/~lxcenter.conf

I have posted about the problem numerous times, websites showing blank, Apache disappearing.  If you have the ridiculously low settings I had, you need to up some of them.  I went with the recommended settings, didn't see any spike in resources, and so far, no more byes.

We didn't need increasing 'Max' value worker/event type of httpd. It's because php-fpm/fcgid/suphp is external process in context httpd process.
