Error description

• When cancelling a PROTECT STGPOOL session on IBM Spectrum
  Protect server, the following messages can be seen from activity
  log on source server which indicates that the cancellation is
  impossible:
  timestamp      ANR2017I Administrator ADMIN issued command:
  CANCEL
  
                           SESSION xxx  (SESSION: xxx)
  
  
  timestamp      ANR1901I The specified session is associated
  with REPLICAT
                           E NODE process 0 and can not be
  cancelled. (SESSION: xxx)
  
  
  The SHOW THREAD (manually obtained during cancellation hang
  period or in a servermon data collection) output shows that the
  main thread for PROTECT STGPOOL is still waiting for work to be
  done (function ProdConsWaitWorkDone), but not recognizing that
  things have been cancelled and are being shutdown from a process
  perspective. Here is an example:

  session after the target server encounters unexpected shutdown,
  crash or any other connectivity issues where the source server
