I complained to my hosting provider about error 500, resellerzoom and this is what they sent me:

Please check it from your end and make necessary modifications to the script. Please feel free to get back to us if you need any further assistance.

I'm supposed to modify MovableType's scripts? Is there anything I can do NOW to reduce memory and CPU usage? Is 4.2 in beta and good enough to use? This is a very unfortunate situation.

Sorry to reply to my own topic, but I've been thinking about this issue:

1. Why is it that I can perform some action and get my script killed, and then go back and do the same thing again 10 seconds later and it works just fine?

2. Could my hosting provider (or the browser) be doing something that causes the cgi script to "hang-around" after the page has been rendered? For example, could the script be being reused over and over without really ending and thus making its CPU and memory usage appear worse than it is?

3. Are there any profiling tools available for Perl that could be used to determine what section is using the most resources?

4. Are there any options that can be placed in the cgi script to limit its use of resources?

You could take a look at the plugins you have installed. Possibly remove some and see if it helps the situation.

Well, I ended up dumping resellerzoom. I'm sure they're fine for regular PHP based blogs, but MT seemed to be too resource intensive for them. They kept killing my processes which caused MT to get an error 500.

I went with a VPS hosting provider where they give you your own virtual machine to run anyway you like and guess what? I haven't had the error 500 since.
