Cpu 100%

recently moved to my own vps. The hardware is HP Proliant DL 380 G6

2 x Intel Xeon E5500 Series Processors, 32GB Ram)

My vps has 3GB ram

After a couple of weeks i started getting 100%, 200%, 400% CPU usage

I run 2 cscart carts on the vps

Statistics module is out and the web sites have less than 400 vistis each per day. Before a had them on shared hosting without any problems

any ideas on what could be wrong?

Not quite enough information. Have you tried using a tool like munin to monitor the server performance? That could give you some leads.

sorry for the late reply. I was too busy for some time

thanks for the reply , i will install it and monitor.
