Anyone recognize this Crash when running WPS Portal viewing a Notes Db?

I am crashing our Quickplace server almost everytime I access a notesdb from the WPS Portal. It does not matter whether it is a Quickplace, iNotes mail file or just a regular Notes database. The stack trace is the same every time.
