As long as you run dirvish-expire before dirvish-runall, there shouldn't
be any possibility of it deleting a new snapshot, because it won't exist

As long as it's a random problem with just a few snapshots I guess that
means you still have a reasonably up-to-date backup of everything (two
days old or better?)

One other thought I had is to check the logs on the clients to see
whether they've been accessed by ssh or rsyncd or whatever you're using.
They might show a rejected connection attempt or a timeout or somesuch.
