How long have you been ignoring these messages for?
[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....
Cheers,
Dave.
