Problem Description: PTF SDF21OX added support for SMF 115 subtype 216 data but inadvertently introduced a loop when processing SMF 115 records that have a subtype not currently handled by Ironstream. PTF SDF21OX supports subtypes 1, 2, 201, 215, 216, and 231. A subtype outside of this list causes the loop.
Resolution: The code is fixed to avoid looping when processing a non supported subtype with PTF SDF21OX.
