The AppDNA queue processor manages a processing queue on the AppDNA server. This reduces the likelihood of deadlocks and resource contention when there are multiple, simultaneous import and analysis processes.
If the Queue Processor has been turned off, depending on the user account under which the AppDNAAppPool is running, the server may not have the permissions to detect and notify the client.
If your application import or analysis is not starting, check the status of the Queue Processor (lower right-hand corner of the Import Applications page) and the status of the Citrix AppDNA Service. Restart the Citrix AppDNA Service manually if neccesary.
