This article also contains a Hotfix for Enterprise Vault (EV) 8.0 SP2, Build 1693, Event 13360 "Not enough storage is available to complete this operation" when the archive task processes if the archive does not have Expiry enabled.
What issues does this hotfix resolve?
When an archiving task begins processing it queries the SQL database to return data on archives that are configured to have expiry disabled. This query could return too much information to be cached on the EV server and therefore the Event ID 13360 would occur stating "Not enough storage available to complete this operation"
