Putty Window inactive after certain time

I am currently processing on a server. I am using Putty to do this. As I am running multiple processes (8), I am using multiple cores as well. After a certain time (2-3 days) I get an error saying:

PuTTY Network Error: Software caused connection abort.

Then my Putty window's status turns to inactive.

Here are my questions:

1. Where does this come from?
2. As most of my files have been processed, is it possible to reactivate Putty in order to continue the processing?

Have you tried enabling KeepAlive in Putty?

tmux and screen are your friends. Putty will still close, but you'll be able to reconnect and continue what you were doing by re-opening the session, provided you haven't rebooted.
