I keep getting error messages sent to me by the hosts of my website. They say that the website is using too much processing resources and they keep suspending it. The issue is they keep sending the errors in unix commands which are totally over my head and when asked what it means they just send the unix commands again. Any help diagnosing the issue would be most appreciated.
The errors are as follows:
Could this be a DOS attack? It's the only thing I can think of.
