FreeNAS 0.7 WebUI cannot access

My FreeNAS installation may sometimes out of memory due to a bug at DAAP server.  As the system exhaust of memory, it will kill some processes, including useful proceses, such as the WebUI.  To regain the control via WebUI without server reboot, we can restart the web interface:

From console or ssh into the server

• /etc/rc.d/websrv restart
• /etc/rc.d/lighttpd restart
