   5     Fix memory leak when parsing SNMP packet (#313)
   6
   7     SNMP queries denied by snmp_access rules and queries with certain
   8     unsupported SNMPv2 commands were leaking a few hundred bytes each. Such
   9     queries trigger "SNMP agent query DENIED from..." WARNINGs in cache.log.
