My experience has always been that Tortoise will handle the re-connection automatically.
What version of tortoise are you using? Make sure you are using at least the latest release.
from tortoise.

I have added the logs from connction and terminate functions.
As you can see, at some point terminate with status :down. And not connection attempts are made.
Any ideas as to why?

My understanding is that the terminate() function should only every be called if the process is about to die, e.g it has crashed due to raised exception. Shouldn't happen for connection drops. See my bug report for details #97. As for why this might be happening I have no idea.

Hi. I am in the middle of moving to another country; so sorry for the lack of involvement from my side. I hope I will get back to tortoise development soon.

Tortoise should be busy trying to reestablish the connection when you receive the ":down" message; you shouldn't need to tell it to reconnect yourself.
My tired eyes cannot spot anything obviously wrong in the connection setup; how about your callback implementation; do you receive something unexpected that is not caught by a pattern match ?
