Rebalancing is taking lot of time on couchbase server (several days)

Dear Team,

i’m also facing similar issue here too, but data rebalance is completed as like normal or as we expect. but some times indexer rebalance is taking more than 4hrs of time. we have ~200 to 300 indexes and replica=1. some times same cluster whole rebalance will complete not morethan 1hrs. but why we are getting that much delay over there.

is there any possible reasons could you share here , need to find what causing this problem.
