Workaround
If the indexing count is stuck at 0, running an index verify or a synchronization against that particular index volume will set the correct value

Solution

There are currently no plans to address this issue by way of a cumulative hotfix or service pack in the current or previous versions of the software at the present time. This issue may be resolved in a future major revision of the software at a later time, but is not scheduled for any release.

Index Volume(s) can randomly show as having 0 items indexed when looking at the count in the Index Volumes Browser via the Vault Admin Console.

The issue can go unnoticed unless it is monitored closely as it tends to fix itself on subsequent updates to the Index Volume.
However, if the count has been set to 0 and the index volume roll-over then the count will stay at 0.
