I have a PXIe-8840 that is shutting down on its own. I have tried it in two different chassis (PCIe-1082) with the same result. I brought it into my office so I could monitor it, and I now have 3 shut downs all within 1 minute of 30 minutes, so my guess is actually 30 minutes and I am just not perfect on logging. I just look at the clock when I hear it turn off, then turn it right back on and write the time down. It is running Pharlap. No keyboard is connected. The fans are running, and it does not feel hot. It has the same software and drivers that 12 other systems here have.
Any ideas?
