Summary:                    SNMP core dumps with greater than 20 interfaces
plumbed up
Description: 
SNMP core dumps with greater than 20 interfaces plumbed up

I have a production server with 24 netwotk interfaces plumbed up. I find
that SNMP refuses to start. 

I am able to reporoduce this on a test server. I keep plumbing up
interfaces using the "ifconfig <iface>:<n> plumb" command. Once the 21st
interface is added SMF immediately moves svc:/network/netsnmpd:default into
maintenance state.

 # svcs -vx svc:/network/netsnmpd:default
svc:/network/netsnmpd:default (?)
 State: maintenance since  2 July 2014 11:29:54 BST
Reason: Method failed repeatedly.
   See: http://support.oracle.com/msg/SMF-8000-8Q
   See: /var/svc/log/network-netsnmpd:default.log
Impact: This service is not running.

# cat /var/svc/log/network-netsnmpd:default.log | grep Stop | tail -1
[ Jul  2 11:29:54 Stopping because process dumped core. ]

# ls -larth /core
