MySQL Replication Health is NOT OK!

What version of the product are you using? On what operating system? mysql-advanced-5.6.19-linux-glibc2.5-x86_64.rpm.zip centos6.3

Please provide any additional information below.

The error log says a slave 192.168.100.34 is replicating from 192.168.100.32, not from a dead server (192.168.100.33). To make MHA work, all slaves have to replicate from a dead server.
