The value of the Notes statistic Antigen.NWall.Backlog maintains the current number of messages between scans.
Each time the NWall processor successfully scans a document, the Backlog is reset to zero. The principle use of this setting is to prevent messages from being queued into SCAN*.BOX indefinately if the NWall Processor has exited or stopped responding.
Use a value of zero to cause redirection never to halt.
Example: NWallHaltScanQ=500
