Unexpected recycling of worker role

Hi all
I've deployed a worker role to Azure and it ran smoothly from February 3rd to February 25th.
On February 26th, the worker role was "silently" recycled.
I would like to understand what happened and if there are scheduled recycling operations or specific conditions triggering a recycle.
The VM was operating normally for both CPU and memory. I couldn't find any error in Event viewer or in stored diagnostics.
This is the only useful message (WAHostBootstrapper.log):
[00002252:00003224, 2015/02/26, 03:52:06.491, INFO ] Sending shutdown notification to client DiagnosticsAgent.exe (2248).
[00002252:00003224, 2015/02/26, 03:52:06.491, INFO ] Sending shutdown notification to client WaWorkerHost.exe (2904).
Thanks
Francesco

Hi Francesco,
Is your worker role instances in recycling status currently? Which region did you host your cloud service?
I saw some mantance log about cloud service /VM from Azure Status dashboard (http://azure.microsoft.com/en-us/status/#history ):
Virtual Machines \ Service Management and Cloud Services \ Service Management - West Europe - Advisory
This incident has now been mitigated. From 26 FEB, 2015 23:00 to 27 FEB, 2015 08:15 UTC a subset of customers using Cloud Services \ Service Management and Virtual Machines \ Service Management in West Europe might have seen failures when attempted to
create new VMs or to restart their existing VMs.
If you always have this issue, please let me know.

Will

How is a Worker Role hosted?

Hi
How is a worker role hosted in Azure. What process is it in?
I'm thinking of how to test locally or an on premise version. Is the Azure host process simply a windows service?
I'm writing a solution that uses the Service Bus for Window Server 1.1 as my customers all use on-premise servers (at the moment). It would be handy if I could create a worker role for on premise solutions :)
Thanks
Graham

Hi Graham,
Thanks for your posting!
Base on my understanding, Azure worker role is used for some services would run in the background to collect, transform, and prepare data. In other words, Azure work role could
executive function to a background processor .
In worker role project, we could see the file named "WorkerRole.cs". The class inherited the "RoleEntryPoint".
public class WorkerRole : RoleEntryPoint
public override void Run()
// This is a sample worker implementation. Replace with your logic.
Trace.TraceInformation("WorkerRole1 entry point called");
while (true)
Thread.Sleep(10000);
Trace.TraceInformation("Working");
public override bool OnStart()
// Set the maximum number of concurrent connections
ServicePointManager.DefaultConnectionLimit = 12;
// For information on handling configuration changes
// see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.
return base.OnStart();
When one worker role instance was starting, it could be executed "OnStart()" method firstly. Then in a worker role’s lifecycle is the "Run" method, typically implemented as an infinite loop, such as "While(true) ".
In fact, if the Run method terminated, the instance would be restarted or recycled again. Please see this video (http://channel9.msdn.com/Series/Windows-Azure-Cloud-Services-Tutorials/Introduction-to-Windows-Azure-Worker-Roles-Part-1).
For your question----" Is the Azure host process simply a windows service?", the answer is that one worker role can be one or more than one instance (VM).
And in your scenarios, Worker role could meet your requirement. In VS, Azure SDK support one project template named "Worker role with service bus queue". Please see this documents:
http://msdn.microsoft.com/en-us/library/azure/jj149831.aspx

Azure Worker Role reboots when adding instance of Web Role

I have a Windows Azure cloud service with a Web Role and a Worker Role. I I have built a website that allows me to perform various management functions against the cloud service (stop/start, reboot instance, add instance, remove instance). All functions are
performed via the web api. My issue is that when I add an instance of the web role, the worker role reboots. Note that this doesn't happen if I add an instance via the Azure portal. The code functions correctly in all other aspects. Any idea how to do this
so that only the role being affected recycles instead of all roles recycling?
My code:
public void AddInstance()
XDocument configDoc = this.GetDeploymentConfiguration();
var ns = configDoc.Root.GetDefaultNamespace();
configDoc.Root
.Elements( ns + "Role" )
.FirstOrDefault( r => r.Attribute( "name" ).Value.ToLower() == this.RoleName.ToLower() )
.Element( ns + "Instances" )
.Attribute( "count" )
.Value = ( int.Parse( configDoc.Root
.Elements( ns + "Role" )
.FirstOrDefault( r => r.Attribute( "name" ).Value.ToLower() == this.RoleName.ToLower() )
.Element( ns + "Instances" )
.Attribute( "count" )
.Value ) + 1 ).ToString();
string encodedString = Convert.ToBase64String( Encoding.UTF8.GetBytes( configDoc.ToString() ) );
this.SetDeploymentConfig( encodedString );
public XDocument GetDeploymentConfiguration()
string uri = string.Format( this.servicePropertiesOperationFormat, this.subscriptionID, this.serviceName, "production", "" );
ServiceManagementOperation operation = new ServiceManagementOperation( this.thumbprint, this.versionID );
var xdoc= operation.Invoke( uri );
var myelm = xdoc.Element( wa + "Deployment" ).Element( wa + "Configuration" );
var mystring= Encoding.UTF8.GetString( Convert.FromBase64String( myelm.Value ) );
return XDocument.Parse( mystring );
public string SetDeploymentConfig( string configurationFile )
string uri = string.Format( this.servicePropertiesOperationFormat, this.subscriptionID, this.serviceName, "production", "/?comp=config" );
ServiceManagementOperation operation = new ServiceManagementOperation( this.thumbprint, this.versionID );
string payloadString = string.Format(
@"<?xml version=""1.0"" encoding=""utf-8""?>
<ChangeConfiguration xmlns=""http://schemas.microsoft.com/windowsazure"">
<Configuration>{0}</Configuration>
</ChangeConfiguration>", configurationFile );
XDocument payload = XDocument.Parse( payloadString );
return operation.Invoke( uri, payload );

Hi,
From my experience, if you add one role instance, the whole cloud service will run in translating state, and this cloud service will stop to working, so maybe this is a future request.

Async / Await in Cloud Services Worker Roles?

Good evening,
I was wondering if and how one would be able to utilize async / await for Azure Cloud Services' Worker Roles? Basically I have background jobs that will/shall run on worker roles, however many of those are performing up/downloads from Azure Storage blobs
and ideally I'd like to await those calls.
So is async/await natively supported for CS Worker Roles (using Azure SDK 2.5) and if so, how? And if not.. is it planned at all?
Thanks,
-Jörg

Hi,
I would suggest you have a look at this thread:
http://stackoverflow.com/questions/15991287/async-await-in-azure-worker-role-causing-the-role-to-recycle
A simple solution is to just do this:
public override void Run()
RunAsync().Wait();
public async Task RunAsync()
while (true)
await Task.Delay(60000);
Hope this helps.

Jambor

Worker Role Store Values In Memory

I am attempting to port a Windows Service to an Azure Cloud Service and a Work Role.
Everything worked, except the difference is in the Windows Service I could start a class that holds two timers that run forever.
From what I saw my Cloud Service created the instance of the class, but it looked like after it was finished executing a new Worker Role instance was created.
Is there anyway to start something and just keep it running?
My Windows Service I kept a property of Running and RunNumber and both of these values are not storing the value in the next run.
I can look up the values between runs in SQL if I need to, just seems like there ought to be a way to process and keep alive.
Thanks if you can shed some life on lifetime of Worker Roles and how to persist items in memory.

Hi Data Juggler,
I suggest that you can define the code in your timer to the method Run() in your Worker Role.
You can override the Run method to implement a long-running thread for your role instance. If you do override the Run method, your code should block indefinitely.
Since your worker role is always running, so the value in it will be persisted in memory.
If the Run method returns, the role is automatically gracefully recycled; in other words, Windows Azure raises the Stopping event and calls the OnStop method so that your shutdown sequences may be executed before the role is taken offline.
For the lifecycle of the role in Cloud Service ,I suggest that you can refer to the link below:
http://msdn.microsoft.com/en-us/library/azure/hh180152.aspx

Is this the best design for asynchronous notifications (such as email)? Current design uses Web Site, Azure Service Bus Queue, Table Storage and Cloud Service Worker Role.

I am asking for feedback on this design. Here is an example user story:
As a group admin on the website I want to be notified when a user in my group uploads a file to the group.
Easiest solution would be that in the code handling the upload, we just directly create an email message in there and send it. However, this seems like it isn't really the appropriate level of separation of concerns, so instead we are thinking to have a separate
worker process which does nothing but send notifications. So, the website in the upload code handles receiving the file, extracting some metadata from it (like filename) and writing this to the database. As soon as it is done handling the file upload it then
does two things: Writes the details of the notification to be sent (such as subject, filename, etc...) to a dedicated "notification" table and also creates a message in a queue which the notification sending worker process monitors. The entire sequence
is shown in the diagram below.
My questions are: Do you see any drawbacks in this design? Is there a better design? The team wants to use Azure Worker Roles, Queues and Table storage. Is it the right call to use these components or is this design unnecessarily complex? Quality attribute
requirements are that it is easy to code, easy to maintain, easy to debug at runtime, auditable (history is available of when notifications were sent, etc...), monitor-able. Any other quality attributes you think we should be designing for?
More info:
We are creating a cloud application (in Azure) in which there are at least 2 components. The first is the "source" component (for example a UI / website) in which some action happens or some condition is met that triggers a second component or "worker"
to perform some job. These jobs have details or metadata associated with them which we plan to store in Azure Table Storage. Here is the pattern we are considering:
Steps:
Condition for job met.
Source writes job details to table.
Source puts job in queue.
Asynchronously:
Worker accepts job from queue.
Worker Records DateTimeStarted in table.
Queue marks job marked as "in progress".
Worker performs job.
Worker updates table with details (including DateTimeCompleted).
Worker reports completion to queue.
Job deleted from queue.
Please comment and let me know if I have this right, or if there is some better pattern. For example sake, consider the work to be "sending a notification" such as an email whose template fields are filled from the "details" mentioned in
the pattern.

Hi,
Thanks for your posting.
This development mode can exclude some errors, such as the file upload complete at the same time... from my experience, this is a good choice to achieve the goal.

How to move worker roles to VM?

I've developed an app that has 3 worker roles and a web role. The client has decided that they want to put this on a VM. I understand how to handle the web role but I am unclear how I convert the worker roles. I've searched but I can't
find anything that directly guides me on what's needed. Does anyone know of a link that would show me how to convert over?

The easiest way to develop a Windows Service in my opinion is using
Topshelf.
You can convert your Worker Role code across pretty easily by
calling the Run code from the WhenStarted event, the OnStop code from the WhenStopped event and the OnStart code from the constructor of your service class.
Alternatively, you can
inherit the ServiceControl interface and implement the Start and Stop methods.
Deploying the service is easy too. Simply get the built files from your console app (a Topshelf service is simply a console app) and
invoke the app (e.g. PowerShell script) with the install parameter, then again with the start parameter.

Running mail server on Worker Role

I'm trying to use a Worker role to setup an SMTP server. I used Visual Studio to provision the worker role, assigned a ReservedIP address to it, setup ReverseDNS, and specified an inputendpoint for SMTP on port 25.
Question, when you specify an InputEndpoint, does it poke a hole in the firewall of the VM? Or does it assign that to the WorkerRole application? I wanted to use a Web Service instead of a regular VM to install an SMTP server, but I'm not having any
luck. I installed SmarterMail on the Worker Role service and cannot get port 25 to respond for Smartermail. It sends mail just fine, but is blocked for inbound SMTP.
Any ideas?
Jim Braun

Hi,
Thanks for Posting.
Yes, Input Endpoints enable External Traffic to be load balanced to your Web/Worker Role VM through the Firewall.

Just prior to the crash...
...it seems like VS 2013 is attempting to log me in to a company server (active directory?). Regardless of my action (providing my login credentials or cancelling the login) VS 2013 then proceeds to crash.
My other computers
On my private laptop that connects to the internet via a private internet connection, the same type of project loads the configuration page w.o. issues (same VS and SDK configuration).
Others have this issue as well
There is also a thread about this on SO, although without a solution:
Visual Studio 2013 crashes when opening up service configuration for edit
Can anybody provide any help about how to solve this, please?
Br,
Claus

Hi Will
Thanks for your answer - I have added my findings below:
The problem apparently stems from the authentication process.
If you are using your company email as username on Azure, the inherent domain name will cause the authentication method to redirect you to your company's Active Directory.
The problem can be solved by choosing a different email as username on Azure.
The problem can also be replicated by setting up a website with authentication using Azure Active Directory. During login through Azure AD, the exact moment you enter the domain name in your username, the login screen redirects you from the Azure AD to the
AD at sts.[email domain name] - and consequently, the login fails. Using a different username the Azure AD authentication works flawlessly.

What are Azure limitations for Websockets in Cloud Services (web and worker role)?

A WebSocket Server should be built on Azure platform with OnPrem connections and have questions regarding limitations for Websockets in Azure Cloud Services - web and worker roles.
Websockets can be configured for Web Sites and limitations are understood, but Azure Websites is not an option.
Nevertheless it is planned to run a web service (without UI - no web site) as a Cloud service which has secure websocket (WSS) connections to OnPrem machines. Websocket protocol is enabled for IIS8 on Cloud services web and worker roles. Azure Service Bus Relay
is not an option.
Questions:
1) Are Websockets supported for Azure Cloud services web and worker roles? we assume yes
2) What are potential limitations from Azure side to support concurrent Websocket connections? We are aware that CPU, memory etc are limitations, but are there additional limitations from MS Azure side?

Hi,
As I know, azure cloud service web and worker role support Websockets, users can connect to the role via the special endpoint, if we use Azure cloud service, I think we can monitor the metrics such as CPU, memory, etc... and scale our cloud service via these
metrics to keep the websockets working, refer to
http://azure.microsoft.com/en-us/documentation/articles/cloud-services-how-to-scale/ for more information about how to scale a cloud service.

Worker Role problems (doesn't work without debugging)

Hello,
I upgraded the OS Version up to 3 last week and everything worked OK. But yesterday worker role stopped working. Windows Azure manager showed that service started up OK. I tried to find problem in code and found out that Worker Role works just great during

Can someone please help? What should I check first?
Thanks!

Hi Alex,
Thank you for advice. I copied the exact connection string from the Azure Management Portal and Worker Role started to work.
Old connection string was:
connectionString="Data Source=xxx.database.windows.net;Pooling=false;Initial Catalog={dbName}; User ID={userName}; Password={password};"
The new one is:
connectionString="Server=tcp:xxx.database.windows.net,1433;Database={dbName};User ID={userName}@xxx;Password={password};Trusted_Connection=False;Encrypt=True;Connection Timeout=30;"
Anyway sometimes (very rarely... once in a 2-3 hours) I get next error:
"System.Data.SqlClient.SqlException (0x80131904): A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL
Server is configured to allow remote connections. (provider: TCP Provider, error: 0 - A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed
to respond.) ---> System.ComponentModel.Win32Exception (0x80004005): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"
Probably do you have some ideas regarding this?
Thanks a lot

Autoscaling Application block for Azure worker role console app not working. Get error as The HTTP request was forbidden with client authentication

If anyone know why I am getting this anonymous access violation error. My webrole is secured site but worker role not.
I appreciate any help.

Hello,
>>: The service configuration could not be retrieved from Windows Azure for hosted service with DNS prefix 'rmsazure' in subscription id **************
Base on error message, I guess your azure service didn't get your certificate and other instances didn't have certificate to auto scale. Please check your upload the certificate on your portal management. Also, you could refer to same thread via link(
http://stackoverflow.com/questions/12843401/azure-autoscaling-block-cannot-find-certificate ).
Hope it helps.
Any question or result, please let me know.
Thanks

Guidance needed please for architecting a scheduled application process (Worker Role vs. VM Role)

I'm close to putting all of the pieces together for an Azure Cloud Services solution that I want to build.
My goal is to build a .NET Library (or perhaps a Windows Service or even a Console Application) that will run once a day to execute dynamic queries against an Azure SQL DB.
There would be 1-x numbers of these query sets that will need to be run during the process, and after each query set an email will be sent out containing data from the query results (which shouldn't be terribly large or processor intensive) to an email
recipient specific to that data set. I plan on using an assigned Office 365 Mailbox as the sender account and email recipients would all be in the same Exchange organization.
I haven't decided on the emailing API yet, but it may require dependencies to be installed on Windows Server (e.g. the MAPI subsystem, AKA the Mail applet in Control Panel - so I can use Redemption which is a third-party replacement for the Outlook Object
Model that doesn't require Outlook to be installed) unless I go with Exchange Web Services or the Office 365 REST APIs.
So my main question is what's more appropriate, a VM or a Worker Role?
Since the processing should only take 5-10 minutes to complete, I'd like to minimize the uptime of the VM or Worker Role and be able to turn it on when the scheduled time occurs, and turn it off when
the processing is done.
I'm also trying to understand how to fit in either the Azure Scheduler Service or the Windows Task Scheduler in the OS to auto-run my .NET application and/or Worker Role/VM.
Any guidance would be appreciated!

Hello Eric,
There is currently no Option for automatically deploying an Azure Role, running it and then Shutting it down or Deleting it. That kind of functionality is possible using the
Windows Azure service Management API which is used by the Windows Azure PowerShell cmdlets.

'Not running in a hosted service or the Development Fabric' exception on deployed Worker role

We are getting this exception after a worker role has been operating fine in production for several weeks. Once this exception starts getting reported, it will keep getting it every time the worker role tries to access anything with the Diagnostics:
Not running in a hosted service or the Development Fabric
Note that the role is full trust, and as I mentioned this in in production on the Azure servers, NOT in debug. The worker role itself does some dynamic compilation, for which it needs to start a new AppDomain. It appears that the exception is
coming from the spawned AppDomain when it occurs. The exception itself is triggered on a simple Trace.TraceInformation call.
What could cause this?
What can we do to recover from this?

Hi,
I have tested this situation in Windows Azure platform and i can not reproduce your exception message, my test code in follwoing MSDN samples and i deploy it in Production status.
The MSDN article (include Appdomain code snippets)
http://msdn.microsoft.com/en-us/library/system.appdomain.aspx .
Base on my understand, the "Not running in a hosted service or the Development Fabric" error message occur when Azure Emulator or Azure development fabirc, because you create a new appdomain in WorkRole, and it may cause permission errors, a similar
