Remember my post about someone keep hitting all my affiliate links and my php files?. If you don't remember you could read it here, Who is 81.176.229.53!!!?. I mean all my affiliate links including some affiliate links that has been down by my CPA network.

Today, My site is going down for several hours, It's give me 500 Internal Server Error. I contact my webhost immediately and here they answer:

Dear Customer,
The error is related to your account using more than 25 processes. We do not allow more than 25 processes for each user account. Once you hit that limit, your account will generate 500 errors. In this case, it looks like your directory or domain, indocontest, is getting a high amount of stuck processes. I've killed the processes, but you'll want to take a look at your WordPress install and make certain you're not running any unecessary plugins, plugins that stall out, or wp-cron.

I don't have any wordpress plugins that stall out or wp-cron. I'm know this guy already doing this from 2 months ago but i figure it out about 2 weeks ago. I'm look at my wp-stats plugins. Here some screenshoot about this guys:
