I have setup a multi source replication in my environment
n1 -> n2 (created n1 as channel replication)
n2 -> n3
n1 -> n3 (n3 will replicate from both n1 and n2 channels)
> Whenever without channel wise replication pt-checksum is working fine.
> Once i enabled as channel wise(only n1, removed the n2 channel) replication (n1->n3) , the pt-checksum is not going through.

pt-checksum is getting to never ending loop in multi-source (channel based) replication :
