simple steps maintaining website

[ebaobao]

Hello,
Can anyone point me in the right direction for maintaining my website so that it runs smoothly. The website has already been configured and is up and running, but there's always issues that make the website go down. I don't know if its the host server problem or if I need to do configuration on the zen end. Just today I got this message from the host:

If you are the webmaster, your account may have gotten this error for one or more of the following reasons:
Your account has used more than its share of the cpu in the past 60 second sliding window.
Your account has too many concurrent processes running simultanously.
Your account has consumed too much memory.
Your site was recently very busy trying to run inefficient scripts.
The solution would be to optimize your applications to use less CPU.
Adding appropriate indeces to your SQL tables can often help reduce CPU.
Using static .html documents instead of painful .php scripts will practically eliminate CPU usage.

My website doesn't have any crazy scripts running or anything, its just a basic ecommerce website. Anyone good suggestions on maintaining the website?

Hi Kim,
The current host I'm using is one of the hosts under zen carts website under certified host. I'm not sure which one to go to, do you have any recommendations? or where should I post to ask this question about which host to pick?
Thanks.
