Can anyone please tell the solution for error "AsyncResult operation exceeded timeout of 00:05:00"?

I am trying to convert Presentation into png images.

// Convert to PNG  
PictureRequest request = new PictureRequest(inStream, ".pptx", PictureFormat.Png, outStream);
IAsyncResult result = request.BeginConvert(SPServiceContext.GetContext(siteCollection), null, null);
request.EndConvert(result);

After 5 minutes it gives this error.

As soon as error is encountered, 4 logs are logged into event viewer as follows,

I have a webservice hosted on sharepoint server which is trying to convert Presentation into images exist on sharepoint site using powerpoint automatioin services.

  • How large is this presentation? If you take a single slide presentation, do you get the same result? – Trevor Seward Jun 6 '14 at 5:41
  • It happens with single slide also. I checked the powerpoint Automation services on sharepoint and those are running, PowerPoint Conversion Service Application and PowerPoint Conversion Service Application Proxy. Also PowerPoint Conversion Service is set to Started in Manage services. I think application is not able to communicate with the automation services proxy. That's why it is giving timeout. I am still clueless over the solution. – DineshS Jun 6 '14 at 11:42
  • I created sample application as described in the following link. msdn.microsoft.com/en-us/library/office/… But this application also producing same timeout error – DineshS Jun 6 '14 at 11:42
  • A couple things I would check: Make sure the Service Application Account you're running the Service App under has Farm Administrator rights which is required for PAS. Also, I have a solution at pas.codeplex.com. You can take a look at Conversion.cs as an example of using PictureRequest. – Trevor Seward Jun 6 '14 at 15:09

The solution is,

  1. In IIS, the application pool under which the Powerpoint conversion service application is running specify the identity of administrator user in advanced settings.
  2. User should be part of user groups WSS_ADMIN_WPG, WSS_WPG, WSS_RESTRICTED_WPG_V4
  3. Add this user to security section of Sharepoint_Config table in sql server

this issue is due to insufficient permissions assigned to the user.
