Webjob continuos execution problem

Question

Hi all.

I need to create an Excel report long-term in the background with the call from a website. The code to use for the call is the following:

QueueClient client = QueueClient.CreateFromConnectionString(connectionString, queueName, ReceiveMode.ReceiveAndDelete);                                
BrokeredMessage msg = new BrokeredMessage(classe);
msg.MessageId = DateTime.Now.ToString("yyyyMMddHHmmss");
client.Send(msg);

Listening is a webjob with execution continues receiving the queue and activates the procedure to create the report.
This is the webjob code and configuration:

static void Main() {

	using (IKernel kernel = new StandardKernel(new MyBindings())) {

		_servicesBusConnectionString = ConfigurationManager.AppSettings["serviceBusConnectionString"];
		_namespaceManager = NamespaceManager.CreateFromConnectionString(_servicesBusConnectionString);

		JobHostConfiguration config = new JobHostConfiguration();
		config.FunctionTimeout = new TimeSpan(1, 0, 0);                
		
		config.JobActivator = new MyJobActivator(kernel);

		ServiceBusConfiguration serviceBusConfig = new ServiceBusConfiguration {
			ConnectionString = _servicesBusConnectionString
		};

		config.UseServiceBus(serviceBusConfig);

		var host = new JobHost(config);                

		host.RunAndBlock();
	}
}


//Function
public void ProcessQueueMessage([ServiceBusTrigger("my-queue")] ReportExcel message, TextWriter log) {
[...]
}

If execution time for report creation is very long, job execution goes to state "Never finished" and start a new procedure (I think it happens after 10 minutes).
How do I leave a single active long execution?

I think webjobs have TimeoutAttribute.Please check that

Hi,

an alternative might be Azure Functions to do the stuff you need.

Also: 10 minutes is pretty long to generate a report and likely beyond the intended scope of Web Jobs. Either optimize the generation code or look into another tooling set to generate it like a seperate VM.
