im relatively new to running my own server and my host don't seem to be giving me up advice or help on the matter either.
I run a very popular website and after doing some twitter and fb posts to over 2 million fans and followers the server really seemed to lagg and take strain.
The server has 2CPU cores and 4GB of ram, 100GB HDD and is running wordpress as the main website. Wordpress has been given more than enough memory to function and i just wanted to know why we was getting such a lagg on our server even during the peak times with our high spec.
google analytics only showed around 200-250 people on the site (using realtime analytics)
so my hosting company told me to check the error logs and i saw this happening quite a lot..
[Wed Jan 30 16:07:18 2013] [warn] [client 18.104.22.168] mod_fcgid: can't apply process slot for /var/www/cgi-bin/cgi_wrapper/cgi_wrapper, referer: URL
what exactly does this mean, and how can i resolve it, does this have anything to do with the lagg?
