MongoDB "Starting new replica set monitor for" message meaning

I have a MongoDB (4.0.4) replica set with 3 members.

The system works well, but the logs are full of the following message:

NETWORK [LogicalSessionCacheRefresh] Starting new replica set monitor for

The message is logged every 5 minutes and repeated 4 times each time.

  1. Why does MongoDB needs to start a replica set monitor so often?
  2. Is this normal or is it a sign of an issue with my configuration?
