  An ABEND0C4 in DSNLCPCR can happen if zparms MAXCONQN and
  MAXCONQW are being used to control DBAT queueing. These zparms
  were introduced with PM43293/UK90325. The default setting for
  both is OFF. The ABEND0C4 and subsequent DB2 crash can only
  happen if non default values are specified.

dynamically updated.
