Disk space is low on the Sync Service machine

If Sync Service is unable to pass reporting log files collected by the hybrid service to Log Server in a timely manner, log files may accumulate on the Sync Service machine, consuming large amounts of disk space. To avoid this issue:

  • Make sure that Sync Service is collecting reporting log data from the hybrid service at appropriate intervals. The more Internet activity your organization sends through the hybrid service, the more frequently log files should be downloaded to avoid large backlogs.
  • Make sure that the Sync Service machine is able to connect to the Log Server machine on port 55885.
  • Allocate sufficient resources on the Sync Service machine for the volume of reporting data being processed.
