If JES2 cannot determine the reason for the reconfiguration, such as if a member requests a reconfiguration and then fails during reconfiguration start-up processing, JES2 will not be able to determine the reason for the request. JES2 then cancels the reconfiguration and issues $HASP255 JES2 CHECKPOINT RECONFIGURATION CANCELLED BY JES2.

If this type error occurs, just restart the failing member. Unless there was a need to reconfigure the checkpoint as indicated by further messages from other members, the problem is cleared up by the restart alone.
