I'm wondering if someone could help me. I purchased an antminer s1 a couple of months ago. Up until a few days ago, it had been mining for about 2 months straight without any issues. Recently, it has started shutting down and by that I mean it stop mining. The whole unit doesn't shut down, as I can still access the web interface and ssh, but it's like cgminer stops working and it will eventually reset itself after a few minutes.

The only change that has been done in the past few months is not even really related to this unit. I switched all my GPU rigs over to x13 and the only commonality between the ant and the GPU rigs are they run on the same circuit. I know, or almost know, it isn't a power issue since the unit stays on and no GPU rigs are affected. I don't believe it's a temperature thing as the mining room actually runs a lot cooler now that I've switched from scrypt to x13. The unit gets not hotter than 45C on each blade. I did just recently try updating the firmware to the most recent one from Bitmain and that didn't help.

This crashes about 3-4 times a day. My problem is I don't see anything in the logs, kernel or system, to show any kind of issue. I don't know enough about how the filesystem is for the any to go looking for other logs so any help in that area would be appreciated. I'm sure there has to be a way to obtain more detailed logs from cgminer or something else to see what's going on. Suggestions?

Add a post here just for future reference (as I'm curious to work out roughly how many are failing): https://bitcointalk.org/index.php?topic=677110.msg7936026#msg7936026 and let us know if you manage to work it out. It sounds like your blades are on the way out, several people are reporting similar things, eventually they will just stop firing up but the control board will be fine. It seems like the S1's have a very short shelf life. Mine last 5 months. And that was with extra fan, and heatsinks.
