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.
