Its taking more than 1 min for Couchbase node to detect Peer couchbase node is down!

Couchbase Server
1

Hi,

There are 2 nodes in a cluster.
1)Shutdown Node1
2)Node2 is taking more than 1 min to detect that Node1 is down and mark it unhealthy

Is there any parameter which we can set to reduce the time to detect failure.?

Note: This is only in case of a shutdown/reboot. If couchbase service is stopped, its taking less time to detect.

Thanks
Sanjay
