I would come back to check on the miner and it would be dead because of the 0 connections on bitcoin.
Not behind a router, and I can easily see 50+ connections upon starting up.
I have changed the setting that put the hard drives to sleep. Hopefully that will stop it?!
Have you got it sort it out ? because I have the same problem and I have tried the fallback nodes but yet it just falls back to 0 in few moments after starting .. and leaving it online for 24 hours does not solve the problem.
I did figure out the problem yes and I posted the answer in my Original Post.
It seems that ubuntu sets hard drives to "spin down whenever possible" or something like that in the power settings... simply removing that "feature" made my Bitcoin client "work" again
