I gave my Mac Mini insomnia!
I had turned on an external FW CD burner to check the readability of a CD that my granddaughter had found and didn't turn it off. I kept wondering why my Mini was suddenly not sleeping at the appointed interval as set in Energy Saver.
Checked the System log for anything unusual and, lo and behold, I found something I hadn't seen before at right about the time it should have gone to sleep:
Jun 17 20:39:35 mail199 com.apple.usbmuxd: _heartbeat_failed heartbeat detected detach for device 0x19d-126.96.36.199:0!
That led me to assume that it was something that wasn't playing nice which is when I realized that the power light was still on on the CD burner. I powered it off and the insomnia vanished.
