The shutdown command might cause the system to hang after it is upgraded to the Solaris 10 10/08 release. The hang occurs while the svc.startd daemon halts system services.
The Sun Java Web Console debug log file at /var/log/webconsole/console/console_debug_log displays if the web console service is cycling, starting and stopping.
Workaround: Type the following commands:
/usr/share/webconsole/private/bin/wcremove -i console svcadm clear system/webconsole:console smcwebserver start
The wcremove command removes the server domain instance that was created for that specific console. When the console is restarted, a new domain instance is created.
