GroupWise Mobility Service not syncing when running GroupWise 14 FTF

GroupWise Mobility Service is not updating devices.
Running GroupWise 2014 FTF (prior to build 116819)

/var/log/datasync/connectors/groupwise-agent.log reports the following errors repeatedly:
INFO [WORKERS_POOL_Thread-6] [gwconnectorlogic:1715] [userID:jds] [eventID:] [objectID:] [] Initial attempt to download attachment failed - will try again (X-GWError-Code: 0x8929)

At the time of writing this TID, there is no public patch to resolve this issue. 

Please contact Novell Technical Services to obtain a more recent FTF to fix this issue.

GMS is unable to retrieve attachments from GroupWise, but then tries over and over again - hogging threads and preventing sync.
