Subject: Replica is going into recovery in Solr 6.1.0

I am using solr version 6.1.0, Java 8 version and G1gc on production. We have 2 shards and
each shard has 1 replica. Suddenly one replica is going into recovery mode and Requests become
slow in our production.
I have analyzed that minor GC max pause time was 1 min 6 sec 800 ms on that time and also
multiple times minor GC pauses.

My logs :

I do not know why long GC pause time happened. In our platform heavy searching and indexing
is performed.
long GC pause times happen due to searching or indexing?
If GC pause time long then why replica is going into recovery? can we set the waiting time
of update request?
what is the minimum GC pause time for going into recovery mode?

It is useful for my problem? :
