Error description

  • Notes Traveler must perform some special processing on plain
    text email bodies before they are synchronized to Apple iOS
    devices in order for the messages to render properly.  A
    performance issue has been identified in one of the algorithms
    used to process these plain text messages and is repaired with
    this APAR fix.  The symptom would be extremely high CPU usage on
    the Traveler server if one or more devices were syncing mail
    messages with plain text bodies > several megabytes in size.
    These types of messages are typically rare and are typically
    generated by machines instead of normal mail correspondence.
    

Local fix

  • If you were experiencing this probelm prior to the APAR patch,
    the only know workaround is to set the following value in
    notes.ini on your Traveler server(s):
    
    NTS_BODY_THRESHOLD=2048000
    
    This causes Traveler to artificially limit all mail bodies to
    2MB in size.
    

Problem summary

  • Though not common, some e-mails have been seen to contain very
    large plain text message bodies which can effect server
    performance processing the message.  These message bodies were
    seen at multiple MBs of plain text content.
    

Problem conclusion

  • The Notes Traveler server has been updated to process these
    large documents efficiently as intended.
