CentOS 5.5, x86_64, drbd 8.3.8.
After running fine for a month, this started a couple of days ago on only
one of three drbd volumes (the other two being fine):

Jan 8 09:54:58 tiger kernel: block drbd11: conn( WFBitMapS -> SyncSource )
which repeats itself continuously. The resync gets to 0.1% and then starts
over. The replication link is a dual bonded GbE point-to-point pair, and
is in full operating condition. All other hardware is fine, and has been
all along. Nothing has been changed. Can anyone give me a clue as to why
this is happening?
