I did something that cause dlmgmtd to core dump:

# svcs -x
svc:/network/datalink-management:default (data-link management daemon)
 State: maintenance since February  9, 2012 06:14:16 PM CET
Reason: Start method exited with $SMF_EXIT_ERR_FATAL.
   See: http://sun.com/msg/SMF-8000-KS
   See: dlmgmtd(1M)
   See: /var/svc/log/network-datalink-management:default.log
Impact: This service is not running.

# cat /var/svc/log/network-datalink-management:default.log
[ Feb  9 18:14:16 Stopping because process dumped core. ]
[ Feb  9 18:14:16 Executing stop method (:kill). ]
[ Feb  9 18:14:16 Executing start method ("/lib/svc/method/svc-dlmgmtd"). ]
[ Feb  9 18:14:16 Method "start" exited with status 95. ]

• I tried to clone a new zone but the one with exact same name already had existed, and
• the source zone zdevel was running
