SNMP requests are handled by the SNMP ENGINE. It is normal for the CPU to go high due to this SNMP ENGINE process. The SNMP process has a low priority and should not affect any functionality on the switch
It is not a bug or to do with your configuation. It is common to see the hulc proccess using high CPU If Catalyst 3750 Switches are connected in a stack. How it works is if there are any configuration changes made to a switch, the hulc running config process wakes up and generates a new copy of the running configuration. Then, it sends to all the switches in the stack. The new running configuration is CPU-intensive. Therefore, the CPU usage is high when building a new running configuration process and when forwarding the new configurations to other switches. However, this high CPU usage should exist only for the same amount of time it takes to perform the building configuration step of the show running-configuration command.
There is no need of a workaround for this problem. The CPU usage is normally high in these situations.
This is a sample output of the show processes cpu command when the CPU utilization is high due to the hulc running process:
