We have a bunch of svc.startd cores on the east-3b HN, all with the following stack:

> $C
f34aedb8`_lwp_kill+0x15(d4, 6, 334, fef5c000, fef5c000, 835f940)
f34aedd8`raise+0x2b(6, 0, f34aedf0, fef5f4c0, 0, 0)
f34aee28`abort+0x10e(835f940, 832c748, f34aee58, 0, 835f940, 832c748)
f34aee58 method_ready_contract+0x232(835f940, 0, 0, 0)
f34aef78 method_run+0x471(f34aefac, 0, f34aefa4, 8355a28, fef5c000, f899a240)
f34aefc8 method_thread+0x179(836fdc0, 0, 0, 0)
f34aeff8`_lwp_start(f899a240, 0, 0, 0, 0, 0)

This looks like we're at the following:

bad_error("ct_pr_tmpl_set_transfer", ret);

Also note that there are a bunch of the following msgs in the svc.startd log around the time of the cores:

Nov  3 13:54:44/176: failed to abandon contract 729828: Permission denied

Nov  3 16:36:24/201: failed to abandon contract 770301: No such file or directory

Here are the messages from /var/adm/messages from around the time of the first core dump:

Nov  3 13:54:43 headnode svc.ipfd[20418]: [ID 404139 daemon.error] _scf_notify_wait failed: connection to repository broken
Nov  3 13:54:44 headnode svc.startd[3915]: [ID 575841 daemon.notice] failed to abandon contract 729828: Permission denied
Nov  3 13:55:25 headnode svc.ipfd[20418]: [ID 404139 daemon.error] _scf_notify_wait failed: connection to repository broken
Nov  3 13:59:53 headnode last message repeated 6 times

We hit this again and were able to figure out what happened. The / file system filled up and init got into the mode where it tried to restart svc.started. That failed three times fast and init went into its maintenance mode. We removed the file that filled root. init stayed in maintenance until we got on the console and did ^D which got it out of maintenance and then it restarted svc.startd and svc.configd successfully.

It would be good if init would log this condition into /var/adm/messages since that is on a different file system and has plenty of space. Currently it is hard to see that init is in this state.
