I'm just on my phone over the holidays, but it kinda looks like the code for this was just updated 12 days ago:
https://review.openstack.org/#/c/619577/

If you're using that new code, I imagine it's possible there could be a bug that wasn't yet caught... If you're NOT using that code, maybe try it and see if it helps? I'm guessing it's related one way or another. If you come to the #openstack-lbaas channel once more people are around (later this week?), we can probably take a look.
