Sorry, I'm afraid I can't anymore. At the time the logs didn't seem very interesting, which was why I didn't attach any to my original e-mail. On the virtualization guests there was a disk error and the drive was remounted read-only. I don't have remote logging, so there was nothing after that. On the OSDs, slow requests accumulated until the daemon suicided.
I'm hoping it doesn't happen again, but if it does I'll send the logs.
