CPU usage rate reaches 100% due to an snmpd process.

Issue

• On a system configuring the following 3 proxies in "/etc/snmp/snmpd.conf", if snmpwalk is run to .1.3.6.1.4.1.211.1, it timeouts. Consequently, CPU usage rate reaches 100% due to the snmpd process.

--------------------------------
proxy -v 1 -c public localhost .1.3.6.1.4.1.211.1.1.1.3.3.2.2.1 .1.3.6.1.4.1.231.2.49.1.3.4.0
proxy -v 1 -c public localhost .1.3.6.1.4.1.211.1.1.1.4.1.1.0   .1.3.6.1.4.1.231.2.10.2.1.14.0
proxy -v 1 -c public localhost .1.3.6.1.4.1.211.1.1.1.4.3.1.0   .1.3.6.1.4.1.231.2.10.2.1.18.1.11.11
--------------------------------

• snmpwalk is run as follows.

# snmpwalk -v 1 -c public localhost .1.3.6.1.4.1.211.1
Timeout: No Response from localhost

• CPU usage rate reaches 100% as follows.

• The behavior of snmp proxy seems to be improper and why snmpwalk timeouts and how to avoid that?
