Error description

  • For a single user, if
    1. the user has multiple devices (at least two but not limited
    to just two)
    2. at least one of the user's devices is using SMS (Android
    Verse), GCM (Android Verse) or APNS (iOS Verse) for push
    3. all of the user's devices are inactive (no syncs or push
    connections to the server) for at least 24 hours
    4. the server is restarted during the 24 hours since all of the
    user's devices' last sync times
    5. the device without the largest data (mail or calendar) filter
    is the first device to connect after the 24 hours and before the
    server is restarted again
    then data on the device(s) with filters larger than the filter
    of the device that was the first to connect after 24 hours may
    be missing.
    
    For example, a user has two devices.  The first device is an
    Android Verse device using GCM for push (it could be using SMS
    or be an iOS Verse device using APNS for push) and a 7 day mail
    filter.  The second device is an IMSMO device (it could be any
    device not of the first device types) and 30 day mail filter.
    The IMSMO stops syncing at 5PM on Friday (for example, the
    laptop was shutdown for the weekend).  The Android device stops
    syncing at 6PM on Friday (for example, ran out of battery or was
    turned off).  The server had routine maintenance run and was
    restarted at 2AM on Saturday.  The Android device syncs again at
    7PM on Saturday.  At this point, the data older than 7 days is
    reaped.  When the IMSMO device reconnects on Monday at 8AM, all
    of the mail older than 7 days has disappeared (the mail still
    exists in the user's mail database and can be seen using
    Notes/iNotes/Verse Web, but the mail is no longer visible in the
    IMSMO client).
    

Local fix

  • Don't let the SMS/GCM/APNS device go offline for 24 hours or if
    it does, make sure the device with the longest filter (IMSMO in
    the example) is the first to reconnect.
    

Problem summary

  • Very rare scenario where a user with two devices with different
    mail filters may experience both devices using the same mail
    filter.
    

Problem conclusion

  • The Traveler server has been updated to resolve this issue.
