Getting below error from last 3 days, This error comes just after Indexes set as backmode.
Log Name: Symantec Enterprise Vault
Source: Enterprise Vault
Event ID: 6848
Task Category: Storage File Watch
The Collector Manager encountered an error.
Reason: The Collector Manager is not running. Check the Storage Service is running and that no previous errors have been logged. The Storage Service may require a restart. (0xc0041ac1)
Would be good to know what version of EV and if you had any changes recently.
Also, grab a dtrace of StorageFileWatch when the Indexes enter Backup Mode. You will be able to attach it here.
