Problem with Scheduling a Email task

I’m trying to schedule an Email task in the Automation Designer. When the scheduled time is reached, it seems that it triggers the task, but it just hangs. When I check in the Windows Task Scheduler, the status of this task is “Running”, and it just stays like that forever. I then have to manually end it. When I run the task manually, it works ok. Please advise

What version of TDP are you using? Do you have many scheduled automation tasks that are run at the same time? If so, spread the apart more. Can you look at the automation log? Is it getting past the compiled stage? Post the contents of the automation log when it hangs.
