Socket close failed for descriptor error

[GigaLim]

I'm using the M5300-28GF3 ProSafe 24-port Gigabit Fiber L3, 10-Gigabit product.

However, I would like to know why this error occurs.

Is there any additional information you need?

Wild guess: Your switch is operating as a DHCP client, and fails to get the time interval (option 58) from the DHCP server.

A little bit vague.

Under what conditions and at about which time does this message appear?

Does this message come up in the range of abut 50% of the DHCP lease time renewal?

Thank you for your opinion.

This error occurs every minute.
I just checked and the time setting for the switch is not set. It's from 1970.

Is this a problem with incorrect time settings?

And there is no other DHCP server setting other than this.

192.168.134.0/24 consists of vlan1 band, which I do not use.

Please give me your opinion

Thank you.
