I suppose that could be it.  The problem is its consistently losing connection on only this machine, with these newer versions of cgminer. No other miners connected to the same pool have the issue, so its hard to see how its a pool specific issue.  The pool is still up according to every other miner connected.  Also when this error occurs, the failover never takes over either ( in cgminer.conf)....

Oh and to clarify, its not reconnecting which is the issue, both the miner and the pool show there are no more shares being submitted. It could very well be coinotron, its just strange its only  happening on this one new miner.  And not trying to failover at least when it does happen...
How often are you talking about? If it's still hashing away, then it HAS reconnected. That message doesn't mean it has lost the connection forever. However if no shares are being returned at that stage, that's because cgminer only reports the response from the pool, not when you actually send them, so my guess is there's some lossiness in your connection. Ironically new cgminer versions do it "the right way" and expose problems that older versions pretended never happened. I had one user who tracked a somewhat related issue to a bad network card/connection and upgrading the driver fixed it.

Network card might be a place to check, I'll see if I can find some updated drivers.  I'm on the same network as my other miners so the outbound/inbound connectivity is good (35mbit/10mbit).  But to answer your question, no it never reconnects and fails to continue hashing, and the pools show that as well.

When I received this message, the miner had stopped and was no longer hashing. However, after updating to the newer version and making sure I have a failover pool specified, I haven't had any more problems (knock on wood).

Thanks for all of your work on cgminer ckolivas.

You know it's the pool dropping out, right? It also reconnects straight away so unless it's happening often and you see the message about shares being lost due to disconnect, it's not hurting. The newer versions just were more reliable in setting up connections (in windows, as linux didn't have the issue that was improved in 3.0.1).

Ran 3.01 last night, unfortunately still had the same issue.  after about 5 hours. I'm gonna try reverting back to 2.11.0, my miners that still use that version haven't had the issue...

Think for yourself
Did you check with your pool op?  Were your failover pools/servers online?

It would help to know what version

I had a couple of my cgminers go offline with the message "stratum connection to pool 0 interrupted", a third however, which was mining on the same pool did not disconnect and kept running fine. I noticed it an hour later...  Huh

I have a failover set up on another pool, but for some reason that did not kick in on either machine.

Has anyone had this issue come up and have you found any solutions? I thought having a failover set up would have prevented my miners frm shutting down...

Thanks for any advice anyone can offer.
