TDP3512 "npname" COMMUNICATION PROBLEM PERSISTS, CURRENTLY RETRIED count TIMES
When NPCOMM DETAIL is ENABLEd and CONFIG NP RETRYMSG is not zero, this message indicates that attempts are still being made to re-establish communication with the network or Teradata Database for the displayed NP. I/O will be retried every minute until communication is restored (the message appears every CONFIG NP RETRYMSG times that re-establishing communication that is tried every minute fails -- so approximately every CONFIG NP RETRYMSG minutes).
This situation may arise either when the NP is STARTed or after communication for a STARTed NP must be initialized. The NP either remains in the STARTing state (if the NP has just been STARTed) or enters the SYNC'ING state (if communication has been lost).
If the Teradata Database is restarting, no action is required. Otherwise, the cause for the NP not communicating should be investigated.
