[30278027.798067] XFS (xvdj): xlog_space_left: head behind tail [30278027.798069] tail_cycle = 1085, tail_bytes = 1041920 [30278027.798070] GH cycle = 1085, GH bytes = 1039296 XFS is emitting that warning several times a second. Isn't that a pretty good sign that there's something not quite right and is worth reporting? Indeed, you are running an old kern (3.2.0-54) which means it won't have this fix: 3948659 xfs: Account log unmount transaction correctly And that's likely to be the source of all your freeze/unfreeze problems because it will eventually hang the log when it's leaked all it's space in the ether....
