due to my very limited experience on this field (see earlier posts
yesterday) take it with a grain of salt, but that looks to me like
self-fencing (ie. dropping out of the cluster and immediately rebooting)
during (probably high) I/O.
I think observing the console (like proposed) right before the reboots
happen might prove this with a explicit message.
