You checked that you are not running out of activity log extents for the
stacked resource?

Do an: echo 1 >/sys/module/drbd/parameters/proc_details

... and have a look at "starving" counter in /proc/drbd ... should
ideally be 0 and definitely not increasing regularly. If it does,
increase the al-extents value for the stacked resource (max is 3833 in
drbd 8.3 ... IIRC)
