(This is a copy of a thread I started in cfml-general. Let's use this one. I'll put a note in the cfml-general one that to that effect.) Arrrggg. We keep getting hit by intermittent template not found errors, and Element EXECUTIONMODE is undefined in THISTAG. Once it starts, there are a lot of them, missing the same file, which is the same one throwing the EXECUTIONMODE error. Clearing the template cache fixes it, but I'm not happy doing manual interventions to get the site back running. Happened yesterday, and again this morning. I've talked about this before, but since I don't have steps to repro not much came of it. We're not saving class files. Two completely different apps, different servers, different domains, one CF2018, one CF2021. Both ran for many years on CF9 without any of this. One of my colleagues has heard rumors that absolute paths for cfinclude and cfmodule are less reliable than relative paths. I'm reluctant to go through these big apps and change that everywhere, just to see if it makes a difference. Does anyone have any concrete experience that it did or didn't help in your case? Any other ideas?

Convert to CFScript? Are these errors constantly coming from 1 part/page/section of your app or randomly from all over? Do you have any code sampling you can provide?
