Scheduled Tasks

We are using v2.3a and have recently run into issues with our scheduled tasks. These no longer seem to run and the following error is being logged:

Source: Scheduler Timer
Event code: TIMERERROR
Description: Message: Thread was being aborted., Stack Trace: at System.Threading.Thread.SleepInternal (Int32 milliseconds Timeout) at CMS.Scheduler.SchedulingTimer.Run())

Any ideas as to what may be causing this?

Thanks.

RE:Scheduled Tasks

Hello,

This error might be caused by a bug, which wasn't fixed until the 4.1 version of Kentico. Could you please try the following approaches?

A) Could you please check the files in ~\App_Data\CMSModules\WebAnalytics if there are all in the right format, if you are using the webanalitics module?

B) Could you please try to follow procedure bellow:

1. Open App_Code folder
2. Make backup of Global.asax.cs file
3. Open Global.asax.cs file in VS or any text editor
4. Navigate to line approximately 667
5. Change this code:

  // Get passive timer and execute
 SchedulingTimer timer = SchedulingTimer.EnsureTimer(siteName, false);
 timer.ExecuteAsync();

to this code

   try
  {
     // Flush the output
     HttpContext.Current.Response.Flush();

     // Run scheduler actively within the request
     string serverName = SettingsHelper.AppSettings["CMSWebFarmServerName"];
     SchedulingExecutor.ExecuteScheduledTasks(siteName, serverName);
  }
  catch
  {
  }

C) Could you please also try to display ~\CMSPages\scheduler.aspx page with and without 'www' prefix in your domain name and let me know what you see on this page?

Best regards,
Boris Pocatko

RE:Scheduled Tasks

Hi,

a) We are not using the webanalitics module.

b) I could not find that code in the App_Code\Global.asax.cs file, the only similar code I could find was:

// If scheduler run request acquired, run the actions
                    if (SchedulingTimer.RequestRun(currentSite.SiteName))
                    {
                        SchedulingExecutor.ExecuteScheduledTasks(currentSite.SiteName, ConfigurationManager.AppSettings["CMSWebFarmServerName"]);
                    }

c) The page displayed - "This page is used for execution of scheduled tasks."

Thanks,
Nicola.
