TDMS - time based reduction - receiver system deletion

Experts,

I'm doing a time based reduction.  I'm on the step "Start Deletion of Data in Receiver System".  It's been running for over 18hours.

But I don't see any jobs running in SM66 on the Central/Control or Sender or Reciever systems.

When I click on the "Task" button, I see it has completed 8,444 of 12,246  sub activites.  There are 3,802 not yet started.

We're on all the latest levels of DMIS and ECC.

Any ideas?

Thanks

NICK
