LO49730: INOTES USERS MAY EXPERIENCE LONG DOWNLOAD TIMES FOR LARGE ATTACH MENTS IN A DAOS ENVIRONMENT

APAR status

• Closed as returned (APAR cannot be resolved without additional info from IBM or customer.)

Error description

• On Domino 8.5 FP1, iNotes save function for a 4 MB attachment
  finishes in less than 2 seconds. The accumulated CPU time for
  the HTTP task is increased by less than 1 CPU second.
  
  After upgrading to Domino 8.5.1, this same iNotes save function
  of the 4MB attachment finishes in 32 seconds. The accumulated
  CPU time for HTTP task is increased by 24 CPU seconds. During
  this time, HTTP task CPU usage is very high, e.g., above 80%
  utilization.
  
  This Issue is specific to DAOS enabled mailfiles. Even with the
  DAOS enabled mailfile it only happens in iNotes, not in notes
  client, and only if the NLO files are encrypted (DAOS default),
  and only if the iNotes template (StdR85Mail 8.5.1 (09/26/2009))
  is accessed via a web browser.
  
  Following are the Fiddler2 and HTTP debug thread logs captured
  while the problem was happening.
