Maximum request length exceeded when trying to save an incident. Certain groups are ok but others are having this issue.
The fix was to go to the System.Group object within Object Designer and remove the invalid collections on this object for incident coll, change coll and call coll. coll could also be named as collection instead of coll.
(7.2. onwards) If when trying to remove the collections you receive the error "Error on saving changes: The DELETE statement conflicted with the REFERENCE constraint "fkey$ui_form_item$att".. " this means the collections are on a window and must be removed from there first. The windows to check are Company, Customer, Group, Supplier and Support Group.
