Cause
Enterprise Vault monitoring is scheduled (by default) to do weekly database index fragmentation scans on all vault store databases. It is seen that the scan gets skipped for certain weeks due to a condition which checks the difference between the last scan time and the current scan time.
Resolution
This issue has been addressed in EV 14.0.1 and EV 14.1.
Issue/Introduction
By default, Enterprise Vault (EV) schedules database fragmentation scans to run weekly on Sundays at 21:00 UTC as part of the built-in monitoring process. Sometimes one or more databases might not be checked in a given week, but they will be checked the following week.
The issue can be seen by checking the ConfigSettings table in each database for the key/value LastCompletedFragmentationScan, which holds the time that the last scan completed.
