Long Syntax: MPC.017 file( line): XID2( xid2_type) failed was validation (network network)
Description: The MPC+ XID2 received failed its validation checks and will be consider bad.
Cause: VTAM may be using a downlevel version of MPC instead of HPDT MPC. Only HPDT MPC (i.e. MPC+) is supported.
Action: Configure VTAM to use HPDT MPC.
Cause: The random numbers in the XID2 exchange were the same in the MPC+ Net Handler and VTAM.

Long Syntax: MPC.019 file( line): conn_string connection was cleaned up by Sequence Manager (network network)
Description: The MPC+ Sequence Manager cleaned up the connection because of sequencing or acknowledgement problems.
Cause: Data got out of sequence and was not able to recover.
Action: The connections should come back and recover. If the problem continues to happen, then check that the sequence timer value for the connection is not too low. Increase the sequence timer value for the connection if it may be too low. The problem could have been due to delays in traffic that the sequence timer value was not high enough.
Cause: Data was not being acknowledged from VTAM in a timely matter.
Action: If data was still flowing, then may need to modify the sequence timer value for the connection.
