2.1.17 working (problem solved) but I have a lot reads on master (95-98%) and slaves get bored. Wrong config? @paulierco How your config works?
My config:
[Read-Write-Service]
type=service
router=readwritesplit
servers=server1,server2
user=mxuser
password=pass
max_slave_connections=100%
master_accept_reads=false
