Azure: Suave sometimes doesn't work with HttpPlatfomHandler and doesn't return

I host my web application on the azure web application using suave and following the recommended guide .


My application works like a charm, until a few days ago something turned out terribly wrong:

The process threw, excluded and crashed, but the HttpPlatformHandler was unable to restart this process, and the following errors were in the event log:

Process '0' failed to start. Port = 30590, Error Code = '-2147023897'. 

and

 Maximum rapid fail count per minute of '10' exceeded. 

I got this error for hours, and at this time my application responded

 502: The specified CGI application encountered an error and the server terminated the process. 

The only way to solve the problem is to restart the web application manually.


I do not understand why the platform handler was unable to restart the process. A successful start is as follows:

 Process '5516' started successfully and is listening on port '29676'. 

So what's with this Process '0' ?
