Did you post the *entire* contents of the SASL log?

The sasl and normal log is all we need.

Quite, but the odd thing here is that this appears to be a transient
error. Rabbit will disable disk monitoring when it fails on startup,
whereas the situation here is that disk monitoring works initially and
then fails at some point. When that happens rabbit will attempt to
restart the disk monitor, and if that fails a few times *then* it will die.
We have some suspicion that the underlying cause might be a system
update, in particular one that installs/updates Erlang. So it is worth
checking that what cron jobs might be running on your system at 6am.
