Couple of dubious ideas.

 * Isn't smartd some kind of error reporting?  I vaguely remember my having some smartd problems years ago, but no details come to mind.  Maybe the informational messages might say something useful.

 * Maybe mutt has filled its memory with enough messages to run into memory limits, although I'd expect a different kind of failure mode.  What does ps or /proc say about mutt's memory usage once it stops showing content?

 * On my mutt, ^o (re-)opens the mail folder in the sidebar.  If you use that, does the problem go away, same as quitting and restarting?

 * I generally do the saem as you, but with tmux instead of screen, and mutt stays up for weeks at a time, although I change sidebar folders many times.  I have two mutt instances running under tnux, one with local maildirs, one with IMAP.
