Azure Virtual Machine terminates session for no discernible reason

Question

I am currently using the Azure Free Trial, and I created a Virtual Machine (Windows Server 2008).

On this VM, I created an ASP page which works fine. However, to process the client's input, it relies on an .NET application running on the machine which checks for inputs passed into a folder by the ASP page, creates the outputs, and places them in a folder for the ASP page to find (when it's finished) and pass back to the client (an image, in this case).

To get it running, I log into the VM with Remote Desktop (as Admin), start the .NET app, and then disconnect from the VM (without logging myself off as a user), which should leave the session, and any applications, up and running.

So far, this is usually all working fine... I can leave the VM in that state and occasionally visit that ASP site, provide some test input, and verify that I get my output. I have, so far, been able to have it all working correctly for several days at a time.

Here's my problem (finally): I recently found the ASP site was not returning the output, which meant the .NET app was not running. When I reconnected with Remote Desktop and logged in, I found that the session had been terminated, so the app was not running. I had to restart it.

Why would it terminate the session after a day or so? As Admin, my "Log off after" setting is "Never", and there are no other Users. Are there other circumstances that would automatically terminate a session? The .NET app is not very CPU or RAM intensive.

Answer 2

Arwind,

I took your advice and got this response

Virtual Machines are in preview(Beta) as of now and we are not that trained on this feature so I would request you to post you queries at forum support, where a dedicated Production team is working to answer your queries related to all Preview features.

https://www.windowsazure.com/en-us/support/preview-support/.

so, I am going to post a somewhat different version of this question to

Windows Azure Platform > Windows Azure – CTPs, Betas & Labs Forums >  Windows Azure Virtual Machines for Windows

At this point I'm more interested in how many people have experience a similar problem.

thanks

Have you verified the health of your VM during that time? You can go to monitor tab and see if there are any latencies or issues with VM.
