If it's single-threaded and you're sending emails, maybe an SMTP connection is getting hung. If neither you nor the far end server times out, it would appear that your program had stopped.

Alternatively, you might have several slow connections, and when you come to look at the progress, it just happens to be stuck on one of them. How long have you left it just sitting there? It might come back after a while.
