(fixed in SNA Server 4.0 SP1)

CAUSE
To support persistent verification, the SNA Server service may be required to remove the password vector from the FMH-5 Attach request received from the SNA Server APPC DLL. In some cases, SNA Server failed to decrement the internal message size of the element, resulting in an access violation when transmitting the message to the SNA Server link service.
