@bennadel This is a topic that we imported from our Google Group so I’m not sure if it actually will notify any of the original people from the thread as I think it auto-created their accounts here.
Regarding the error, do you have any idea what’s in the form scope, what content type it is, or have a standalone page that can be submitted to reproduce the issue? I’m assuming there’s some massive amount of form data that’s taking a very long time to URL decode. Does the FusionReactor profiler show any other parts of Lucee that are spending a lot of time running?
