Please see this document for a information on the code fix for this issue: NFA Harvester Buffer Patch

If you cannot upgrade or patch your enviornment:

  1. Stop the "CA NFA Harvester Service" and delete all *.NTA files from the x:\CA\NFA\Netflow\datafiles\HarvesterArchive
    Make sure you are deleting the "*.NTA" files (with "T" for "Template") not the "*.NFA" files.
  2. Start the "CA NFA Harvester Service" you stopped in step 1.
