[DRBD-user] Meaning of assertion in drbd?

I'm running a 3.4.103 kernel (with RT patches, if it matters) and I recently saw 
the following error in the kernel logs:

block drbd0: ASSERT( epoch->flags == 0 ) in 

I can see that this is an assertion failure in the WO_bdev_flush/WO_drain_io 
case of receive_Barrier().  However, I'm not totally clear on the implications. 
  Could someone explain what this means and how severe it is?
