Error description

• Starting with IBM Storage Protect Server 8.1.6 an Object Agent
  service was provided to allow Clients to store data on the
  server using the Amazon S3 protocol.
  
  The IBM Storage Protect Object Agent is observed to be slow when
  
  processing client requests using the Amazon S3 protocol list and
  
  delete commands.
  This only becomes noticeable when millions of objects are stored
  
  on the server.
  As an example, the ListBucket command sent by an
  IBM Storage Protect Plus vSnap server to the
  IBM Storage Protect server is expected to last a few seconds
  even when the target bucket holds millions objects.
  It was observed that it could last much longer for example over
  5 or 10 minutes.
  Since the ListBucket command is frequently used, the impact of
  the slowness can become very high and cause an archive or copy
  to cloud operation to last many hours beyond the expected job
  duration.
  
  The impact of the slow deletion command was observed to cause
  delayed expiration tasks to delete the expired objects from the
  target bucket.
  
  IBM Storage Protect Versions Affected:
  IBM Storage Protect server 8.1.6 and later
  
  Additional Keywords: SP, Object Agent, S3, slow, hang,
