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](https://bitcointalk.org/Smileys/default/huh.gif) 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.

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

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...

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).

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.

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.

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.

Got hit again by this pool disconnection message. Hashing has stopped and my pool info confirms this. I mine from a remote location, so this is really painful. It has happened now on three out of the four machines that I mine on.
I don't think it's a network card issue. I'd switched to BitMinter for a while and was using their java app, and didn't have any connection problems at all during that time.
I'm in a Win 7 x64 environment with the latest version of cgminer if that helps.

Exact same problem here. Win 7 x64 Was on cgminer 2.11.4, just tried 3.1.0.
Mining with x2 7970s - CG miner seems to lockup, doesn't hash and won't take keyboard input. Always reports a stratum connection interrupted before going down.
Had this problem a few times earlier this month. Then has been stable for 14 days or so. Now last couple of days its 4-5 hours max, then it hangs.
Mining at Bitminter pool with a failover pool set to BTCGuild. It never fails over, it hangs before. after saying stratum interrupted and then lost shares. A restart of cgminer restores everything working again (till next time).
I suspect the problem trigger is instability in the stratum connection as it has happened each time Bitminter restart or goes down. I'm contemplating setting up a local stratum proxy to try to circumvent the problem until this is fixed.

I'm getting this, too. Running 3.1 on windows, and 3.0 on linux. Of three rigs, 1 windows and 1 linux both went "pool 0 interrupted" and ceased mining. The third rig kept on mining. Neither of the two that "interrupted" failed over.
I'll try setting up a local stratum proxy, but I'm not convinced it will help.
Thanks CK, cgminer is a terrific tool. The new release is packed with updates!

So did anyone found solution for this issue? I see that most of us are on Bitminter and using multiple 7970 cards?
Could this be 7970 specific problem?

Possibly, still no resolution here ![Angry](https://bitcointalk.org/Smileys/default/angry.gif) Ran stable for 36hrs before locking up this time. Haven't gotten around to setting up a local stratum proxy yet, but have switched pools to BTC guild temporarily to see if that's any more stable.
