No idea if it could be related, but I have now a habit of investigating the inter-machine time sync mechanisms (usually NTP) fairly early in 'mysterious freeze' situations.

Found that to be a problem in a few situations, and in one case the two NTP servers I used were themselves out of sync, exasperating the symptoms.
