My new WD My Cloud (product of Thailand) has been nearly perfect for almost 5 days, and then the My Cloud locked up while I was checking it out and running top this morning in an ssh session, and awaiting the beginning of a Safepoint process with less than 31 seconds to go before it was to have started to see how much CPU it would use.
Top Stopped working at 6:59:29 AM or just thereafter, I had just scheduled a Safepoint for 7:00AM because the one overnight said on the web interface that the last one run was at about 5PM yesterday evening, so I thought that was weird. The only active process was convert which was going through my pictures making 1024x1024 thumbnails it would have seemed.
Also note that yesterday afternoon I turned on the Drive Sleep feature for the first time. I had been keeping this off due to the reports of locking on the forum and decided that things were stable enough to try.
To add to the issue, the Safepoint did run according to the email that the system sent to me last night:
Event description:Your safepoint MyCloudThePriceFamily1 on the external share on WDMyCloud was updated successfully.
Event time:02-04-2014 12:03:28 AM
Convert was doing something like this at the time:
convert -size 1024x -define jpeg:size=1024x1024 etc.
All of the following were true at lockup time.
1) Could not find device from the Explorer
2) Could not Access the Dashboard
3) Could not Ping the Device
4) The My Cloud IP address was present in the Routers routing table
Router Name and Model - AT&T Uverse 2Wire see details below
Is the My cloud connected directly to the router - yes
How often does the device disconnect - first time since I bought it last Wednesday
How often does the device disconnect: Once so far
Does it disconnect after a specific set of actions - hard to say,I was within less than a second of a Safepoint beginning
LED color when offline - Solid Blue
From the Dashboard - But of course it was locked up to at this point, but it did say:
Content Scan Status - Idle

7. ISP: AT&T Uverse
8. Internet type (Cable/DSL/fiber/etc): Uverse DSL
9. Backup/NAS software on computers? (Smartware, Windows Backup, Time Machine, QuickView, etc.): Smartware on one so far only used it once. Usually use Linux.
10. Antivirus software on the computer? If so, provide details.: Usually use only Linux, but have one Windows machine using AVG Free, was not even on at the time of the lockup
11. Firewall software on the computer? If so, provide details.: None
12. Is there a USB drive attached to the My Cloud? If so, provide details.: WD My Book 4TB
13. Are you willing to work with WD for additional debugging / log gathering efforts? Yes tell me what to collect.
I had three Windows executables in my personal directory and media serving was turned off on all directories except for Public. I also had a single SmartWare backup from a PC that has been offline for days.
/var/media/external is a 4TB My Book drive for saving Safepoints only.
I did notice that the system was using a few MBytes of swap, which I had not seen before.
All web browing and internet remained available to my other Linux machines during the WD My Cloud lockup.
My router specs:
Two Wire AT&T Uverse Router with wireless
Time Since Last Boot 59 days 4:23:06
DSL Modem 8.4.C
Additional Notes: I have updated to the latest firmware as a result of this event and have been up for a little over two days. I have also turned off the Drive Sleep mode as someone else reported success with this change.
Further notes: After running for 4 days, 5 hours, and 22 minutes, without incident on the latest firmware, I brought back the lockup by turning on the Drive Sleep mechanism. I turned Drive Sleep back on because I wanted to make sure it could work without a lockup before my 14 return period ended. At 4 days, 16 hours, and 48 minutes the top that I had been running from my Linux desktop locked, but I suspect that it really was having issues earlier as it would not respone to access by my Nexus 7 yesterday evening before I went to sleep. So on my WDMyCloud drive sleep is seemingly related to the lockup.
