Bizarre activity

Hello, all,

Our public facing page has recently developed some bizarre activity.

For days it will run with no issues, then it will suddenly start generating error emails stating that a CFOUTPUT tag is exceeding the allowable time limit for a few hours, THEN it will start sending emails to us indicating that a CFINCLUDEd file cannot be found (the file that was originally exceeding the allowable time limit.)

Specifically, we have a file called trans_form_new.cfm.  It is a cost estimate request form.  It CFINCLUDEs a menu from another folder.  The menu is the file that starts taking too long for a CFOUTPUT tag to complete.  After a few emails stating the CFOUTPUT tag is exceeding the allowable time, we start getting emails from trans_form_new.cfm stating that CF cannot find the /otherFolder/menu.cfm file that is clearly present.

I am not aware if the CF service (or the CF server) is being restarted during any of this.  I _am_ aware that we have recently been applying patches, updates, and hotfixes.

Any thoughts on this issue appreciated.

V/r,

^ _ ^

    I've seen similar issues when CF has too much load to handle. The CFINCLUDE location is obviously there, but CF complains about not being able to find the file. My unfounded suspicion is that there's some sort of Windows file locking issue underneath all this (I've only seen this on Windows) but like I said, it's an unfounded suspicion.

    Thank you for the suggestion, Dave.  But I cannot think of any scenario whereby any file is being locked.  Although I do find it interesting that you have experienced this only on Windows servers, and not Linux.

    Well, part of that might just be because that's where I've been working. The formal name for that is, I think, the "streetlight effect".https://en.wikipedia.org/wiki/Streetlight_effect

    In other words, I have more customers using high-load CMSs on Windows than on Linux, and so that's where I've seen those errors.

    But also, Windows file locking works in mysterious ways. Sometimes, files in Windows are locked even though there's no apparent reason for that to happen.
