This morning Site5.com shut my domain down, which is here down and sent my reseller hosting guy this e-mail.
My name is Graham McMillan and I am the Chief of Support Operations at Site5.
Your account was shut down because you were causing problems for dozens of other websites on the server. I think you would agree it is not fair to have one website cause problems for dozens of other customers sharing a server. Your site was shut down in order to rectify the issue, which it did.
As Dragan said, your visitor traffic is normal, so there must be some other problem with your installation as it is not normal for Wordpress to be using that much:
It looks like your theme is broken and it's causing an endless loop which uses all of the CPU resources:
[20-Jan-2011 15:11:42] PHP Fatal error: Maximum execution time of 30 seconds exceeded in /home/k8cpa/public_html/wp-content/themes/atahualpa361/functions/bfa_postinfo.php on line 187
[20-Jan-2011 15:12:16] PHP Fatal error: Maximum execution time of 30 seconds exceeded in /home/k8cpa/public_html/wp-includes/formatting.php on line 1148
The "/home/k8cpa/public_html/wp-content/themes/atahualpa361/functions/bfa_postinfo.php" script would be a good place to start.
As a test, I disabled that specific script completely and the resource usage problems went away. There is some kind of problem in that script.
Your site has been re-enabled, but I cannot guarantee it will stay up as long as that problem exists.
Chief of Support Operations, Site5.com
For the record, I DO have a sticky post up. But something is not right. Site5.com only shuts you down, if something is badly borked and something is messed up!
P.S. I'll come back when it is fixed!
