Unable to start dfservice, Compute emulator is shutdown

Question

Hi,

I have created a test application and a Windows Azure deployment project.

I am using Windows Azure 1.6

When I am running the application, after some time it is giving me error 'Unable to start dfservice'.

I set the environment variable '_CSRUN_STATE_DIRECTORY' to a path on C drive. Reboot the system.

Under administrative account I ran the command prompt and run 'CSRun.exe /devfabric:start' to start the emulator. but no success.

It is still giving me 'Compute emulator is shut down'.

Please help me to resolve the issue.

Thank You

Answer 1

Hi,

Please change '_CSRUN_STATE_DIRECTORY' to a folder that under the C drive, do not let this variable end with slash (\). Such as C:\test.

Have a try.

Respected Sir,

As per your instruction, I set environment variable to "C:\TempSetEnvVariable" path where it creates file "_nextid" CNT file.

But still it is giving me 'Compute emulator is shut down'.

I am using "Windows 7 - 32 bit)

Please help me to resolve the issue.

Thank You

Answer 4

Does it matters whether I am using 32-bit or else 64-it ?

Because my processor is 32-bit only.

Thank You.

Answer 5

64-bit system is recommended, you have to do extra installations in 32-bit system to make azure works, please refer to this article and check if some hotfixed has been installed in your machine (In "System requirements"):

Just for a doubt, can Azure emulators work fine at your computer?

Answer 6

Storage Emulator works fine but "Compute Emulator" does not.

The hotfix given does not apply to my PC.

Thank You.

Answer 7

Hi,

Did not get some more details exception message during the compute emulator shutdown? For example, create a simple hello world application in local and run it (Set Azure project as the startup project). I believe more information can help us fix this problem.

Answer 8

The first screen shows the application start error message. At first the Compute Emulator starts and after seconds of time it suddenly shut downs.

After a min or two, the second error message displays "unable to connect to dfservice" and there application stops.

Thank You.

Answer 9

Dear Sir,

did you get those screens ?

Thank You.

Answer 10

Yes, the screens are visible. Could you confirm if the user account name that you are logged into contains spaces?

Hello Amol,

It looks like a strange problem, you compute emulator could not work normally, as far as i know, Windows Azure emulator will use ports 12000-12002, would you like to check if these ports was already in use? If so, please try to modify DevFc.exe.config file with other ports:

Resolution: 

1. Determine if any of the following ports are being used by a non-Windows service: 15095, 15096, 15097, 15098, 15099, or 15100.
2. Navigate to the installation directory of the Compute Emulator. By default the Compute Emulator is installed at C:\Program Files\Windows Azure Emulator\emulator\devfabric.
3. In the DevFc.exe.config file, locate the add port entry that contains the conflicting port value and modify the value to use a non-conflicting port. The DevFc.exe.config file entries that can be affected are:
   
   
   • <add key="ManagementServicePort" value="15095" />
   • <add key="RepositoryServicePort" value="15096" />
   • <add key="AgentCallbackPort" value="15097" />
   • <add key="AgentPort" value="15098" />
   • <add key="PxeResponderPort" value="15100" />
4. In the DfService.exe.config file, locate the dfservice element and modify the ManagementServicePort or RepositoryServicePort attribute to use a non-conflicting port.
   
   
   • <dfservice    ManagementServicePort="15095"    RepositoryServicePort="15096"   />
5. Press F5 to restart the application or run the CSRun Command-Line Tool.

If it still not works, find this path

 c:\users\<username>\AppData\Local\dftmp\DevFCLogs 

to see if there's more details logs about this error.

You can also try to re-install Azure SDK or test the application in another machine and have a try.

BR,

Arwind

Thank You.

Answer 15

Hi Amol,

I experienced the exact same problem you had and spent 4+ hours trying to figure it out and finally came across the problem.

My WCF RIA Services was out of date, by quite a bit.  I updated to the same version my colleagues were using(since they weren't having this issue).  My version was 1.0.numbers. and I updated to version 4.1.60144.0 and everything started working again.

Good luck to you sir.
