Yes, I upgraded all of the real server backends in the idd.unidata.ucar.edu
cluster to current versions of the LDM on Saturday (5 are currently
running LDM-6.11.3 and one is running LDM-6.10.1).

Question:

- have you checked your REQUESTs on metfs1 to make sure that you are
  not redundantly REQUESTing the DDPLUS datastream?

  Please remember that a DDPLUS request will be redundant if you
  are REQUESTing any of the following:

  WMO         == HRS|IDS|DDPLUS
  UNIDATA     == WMO|UNIWISC
  IDS
  DDS
  PPS
  IDS|DDPLUS

If you are REQUESTing DDPLUS redundantly, removal of the redundancy will
eliminate the disconnecting messages you are seeing.

Cheers,

Tom
