As BrowserUk pointed out, if you let us know why the files failed to close, that would help. I'd like to add that there is no "best way to manage" this problem. It depends upon what you are trying to do, why you are trying to do it, what happens if you don't do it, etc.

Aside answering the questions above, here are some others:

• If you use source control, check what changes have occurred to the offending programs when the failures started to occur. Rarely do problems just "start happening".
• Is this really a cgi environment? Any chance that it's mod_perl, ISAPI, or something else that might have a bearing on the problem?
• Can you show us any of the offending code?
• You mentioned that this is a recent problem. Has anything on your box changed? Is there any scheduled maintenance you skipped? I know the latter question seems weird, but if you don't know what is causing a problem, then everything is suspect.

Cheers,
Ovid
