[KeyValueEndpoint]: KeepAlive Threshold reached - closing this socket proactively

Hi, I am trying to asynchronously upsert 20K records in couchbase and started getting

[KeyValueEndpoint]: KeepAlive Threshold reached - closing this socket proactively.
[KeyValueEndpoint]: Got notified from Channel as inactive, attempting reconnect.

exceptions. My app is spring boot app and using RxJava to upsert a batch of records asynchronously. Any idea why this might be happening?

Any idea why this might be happening? Is there any setting in JDK that I can tweak?
