ASL_AMD PC fails after about 2 weeks

I am still trying to get ASL_AMD 1.01 to run reliably for a remote site. I’m using an AOpen DE7000 with an 8Gb SDD. It is running 2 nodes. It is perfect for about 2 weeks, then fails with the URI lights flashing slowly ( see link to video ) and I lose the ability to SSH into the system. This has happened twice now, and the system has to be rebooted. I don’t see any help from the error log. Any suggestions?
