Form character limit issues

Having an issues with Percussion created forms submitting. The form submission is unsuccessful and redirects to my defined error page upon submitting with to many characters. The max char size is not defined in the box so there is no limit placed at this time. I also tried to set a huge limit while troubleshooting to 50,000 characters but the form would not save and stall Percussion.

There is no error message reported to the user to let them know the reason the form is not submitted. I don’t have specific numbers as to when it breaks but 647 with spaces works but 719 with spaces breaks… so somewhere in between there.

Help!

This is on a text box field type FYI.
