For the past few days I've been running my unRAID box with the drives spun up all the time, as I've been doing some long SMART tests on some of the drives.  Anyway last night I did a clean parity check, so today I replaced one of the drives and rebuilt it without incident.  About 45 minutes after the rebuild had finished I went to the "Settings" page and changed the "Default spin down delay" back to 15 minutes (from Never), when I hit "Apply" the page greyed out and the web interface stopped working.

 

I looked at the syslog through unMENU and saw that some odd errors had just appeared (see end of the attached full log).  At this point I just did a "shutdown -r now" from the telnet interface and the system restarted ok.

 

Here is the relevant excerpt, you can see it immediately started to spin down the drives and upon spinning down drive 4 it ran into some sort of problem:
