Hi,

Thanks for your mail, I read the patch and have some questions:

1. Is this bug easy to repeat (seems need lease owner committed by a
host is not the lease leader)?

2. I find the commit 6501351b742 introduced bug is released with
3.6.0, if I want to fix it, which is recommend, make a master build or
downgrade to 3.5.0?

Thanks again,
Damon
