About ARP resolution in DHCP relay

[Translator]

I have a device that has been configured as a DHCP relay agent.
I looked closely at the logs for this device.
I found the following log output when an IP address is assigned via DHCP.

%ADJ-5-RESOLVE_REQ_FAIL: Adj resolve request failed for X.X.X.X on VlanXXX

I believe this is a log that occurs when ARP resolution is not performed correctly.
However, in reality, the IP address is assigned correctly via DHCP, and the IP address is recorded correctly in the ARP table.
Is this log expected?

You have equipment configured for DHCP Relay Agent.
While I was watching the logs on this device, a question occurred.
The following logs are output when DHCP is used to withdraw IP addresses.

%ADJ-5-RESOLVE_REQ_FAIL: Adj resolve request failed for X.X.X.X on VlanXXX

We recognize this is a log that occurs when ARP resolution is not done correctly.
However, in practice, DHCP is correctly withdrawing the IP address and the ARP table is correctly filled with the IP address.
Is this log output as expected?

I never try but server and/or client is use GARP to check if this IP is use by other host or not.

If GARP is failed then IP can be assign to new host. 

So I think it normal

Thank you for letting me know!
I now understand the communication flow very well.
