How to eliminate FATAL error

Hi.

In order to monitor the status of Vertica, I am checking the FATAL message in vertica.log, and the following message is output approximately every 5 minutes.

2020-09-14 14:11:41.885 Init Session:0x7fec52ffd700 <LOG> @v_bhdb_node0001: 00000/2705: Connection received: host=192.168.183.61 port=42946 (connCnt 7)

Why do I get this kind of message?
Please answer if you know the cause and solution.

Thanks.
