Ideally you shouldn't have to do either. PHP scripts automatically
close all resources upon termination, unless you've explicitly asked
them to do otherwise.

I've rarely encountered a 500 error using PHP, typically it crops up
with Perl scripts. In most situations, PHP will throw its own errors,
which are descriptive enough to trace the source of the problem.
(Granted, I just posted a few moments ago about an exception to this
case...)

Database as in...? MySQL? How much traffic are you getting? Are you
using persistent database connections, or normal ones?

I'm not familiar with webfarm; with any luck, they give you a PHP
error log, or they send PHP's errors into Apache's error log. Whatever
error logs are available to you, check them religiously.

Jerry did that one justice in his response.
