It may help to hear what web server you’re using, and what version of FW/1, and what specific Lucee 5.4. It may proven pertinent to someone else seeing this.
And as you’d commented at the end of a related thread on the matter, did you consider some of things offered there? Granted that was folks using Mura—and as you’ve not mentioned it, I’ll assume you’re not.
But they were using FW/1, and the issue had to do with how the mura fw1 plugin was having issues that seem potentially related to your own code. Perhaps what they did could help guide you.
I appreciate you may hope someone just “has a fix”, if this “may be a known issue”. That’s the reason I asked the opening clarifications. I won’t likely have much more to offer. Think of this as me “priming the pump”.
