as per cisco.com error message decoder:

Error: %DHCP_SNOOPING-4-QUEUE_FULL: Fail to enqueue DHCP packet into 
processing queue: [chars], the queue is most likely full and packet will be 
dropped.

Explanation: DHCP packets are coming into the CPU at a much higher rate than the DHCP snooping process can handle them. These unhandled DHCP packets will be dropped to prevent system from denial of service attack.

Recommended Action: No action is required.

Thanks John for the feedback. Is there any impact on user or server side?
