While parsing the message, one of the following conditions occurred:
The message content was inconsistent with the "Message Length" in the message header.
The IMSI contained in the User-Name AVP was considered invalid due to length.
The MSISDN contained in the MSISDN AVP was considered invalid due to length.
These protocol errors can be caused by the originator of the message (identified by the Origin-Host AVP in the message) or the peer who forwarded the message to this node. Collect a trace containing the GGR, and determine which node is causing the invalid data.
