Adrien, 

Thanks for you reply. 

Yes, I'm using 2.4.16, and below my the configuration:

# service AND an understanding of referrals.

Hy Hu,

I am pretty sure it is not supposed to be like that. I had a similar problem when testing MMR with more then 2 masters, which isn't your case.

Are you using 2.4.16 ? Could you please attach your configuration ?
