device will freeze with snmpwalk after OID

.1.3.6.1.2.1.11.30.0 = INTEGER: 2
.1.3.6.1.2.1.11.31.0 = Counter32: 0
.1.3.6.1.2.1.11.32.0 = Counter32: 0
.1.3.6.1.2.1.31.1.5.0 = Timeticks: (1216) 0:00:12.16
Timeout: No Response from 10.30.4.10.

so, device will go in invalid state, freeze, reboot, or simply inacesible

snmpd proces inside device will hang whole device

any solution ?

could not try with older FW because
>3. After installing this firmware, the CPE will not be able to install lower versions of firmware.
