• Closed as program error.

Error description

• The current form of the LLDP Layer stitcher has some OQL joins
  in it. It's joining on the LLDP /DefaultLLDP  returns and
  working entities.
  If the amount of data from LLDP/DefaultLLDP agents and working
  entities is big (thousands of records) it could cause a slow
  processing in the stitcher and is
  slowing the discovery processes in final phase
  

Local fix

• N/A

Problem conclusion

• Resolution is to modify the stitcher not to use joins and to
  improve the algorithm used.
  The populate LLDP lookup stitcher populates a lookup table to
  simplify processing. The process LLDP remote data stitcher
  processes a set of LLDP data and determines the correct
  connectivity.
