Bluescreens may occur intermittently on servers running the FSA Agent when these servers are being backed up by a backup application using Microsoft Volume Shadow Copy Service (VSS).
A crash dump analysis in Microsoft WINDBG shows the following.
STACK_COMMAND: .cxr 0xfffff88002b16110 ; kb
This issue has been addressed in the following release:
Enterprise Vault 9.0.4
Note: This registry value is already present in Enterprise Vault 10.0 and as such the root cause of the issue is resolved in this version.
1. Open the registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EvFilter on the affected File Server
2. Right click in the right pane and select "New -> DWORD value" Enter the name as "IncrementVPBCount" and set the value as "1"
3. Restart the machine.
Alternatively, modify the backup application so that VSS is not used in the backup job.
