thats why it is a good idea to throw in an extra network card & cheap hub then split it off,
or re-direct the miner traffic via WIFI to a separate hub......, keeping the big traffic on a switch.

Personally I also keep a mobile phone on standby with a bluetooth network redirector setup in the controlling SBC, should it loose connectivity via cable/WIFI....

The fact connection interrupts is not a problem itself. The problem is that cgminer never recovers after interruption for us.

Yup im still having same problem in every version of cgminer, ya cgminer never recovers after it got interrupted stratum, so no matter failOver setting i set, it never be recover

I upgraded to 3.3.0 and was still getting stratum connection interrupted messages on all 3 pools.
On the same home network my miner is hooked, I was running a large file copy (50+ GB) to the NAS that was hogging network bandwidth. Once that completed, the stratum interrupted errors disappeared.

Seems to still be an issue. I upgraded all 6 of my miners to 3.2.2 last night and this morning 2 of them were hung with the last entry being "lost xx shares due to stratum disconnect". I am using BTCGuild.

I believe I may have found the cause for this issue at long last and I have put generic fixes into cgminer 3.2.2 which was released yesterday that should hopefully address them.

Latest cgminer version is 3.2.1. Stratum changes went into 3.2.0.

Now problem became even more "funnier". I switched backup LP pool with Stratum pool. So main pool is LP one. Now cgminer hangs when backup pool reports about new block!

Have this annoying problem. Updated to 3.1.1 - nothing changes, I still get stratum connection to pool 0 interrupted with cgminer becoming unresponsive after that.
May the cause be that I have non-stratum backup pool?

Thanks for the info. It looks like CGWatcher should do the trick. Also good to know I'm not the only one with frequent upsets.

My final answer (for windows) is using CGWatcher: http://manotechnology.blogspot.com/p/cgwatcher.html

CGWatcher coupled with failover configurations in cgminer, will handle stratum disconnections, sick cards, drivers restarting, shares not being submitted, mhs decreases, and more. Configure windows to start cgwatcher on startup, save cgminer settings to default conf, configure cgwatcher to start cgminer automatically when cgwatcher starts, check all montior boxes (except restart based on hours, and except start/stop by schedule, and let 'er rip.

Cgminer poops out due to sick cards and network issues on my windows rigs, and cgwatcher restarts cgminer automatically. My worst rig restarts cgminer about four times a day. My best rig restarts cgminer about once every two days.

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.

I've had the same experiences. I've got 2 rigs mining at separate locations. One is a single 7970 running 3.1.0 and the other is running 2 7970's with 3.1.1. The rig running 3.1.1 seems to drop out more often - about twice a day. Is it a stability issue? I'm running the single card rig stock (69 degrees C), the other rig is running both cards @ 1000MHz core, 925MHz RAM, 70 degrees C. Is this issue because the cards are throwing garbage at cgminer, or a network connection is flakey, or something else? They always seem to drop out at the worst times - like 5 minutes after I go to bed...

If no one has a solution to the cgminer issue, does anyone have a good way of alerting you if a miner stops submitting shares?

I'm using 7970s too, with stock voltage. cgminer does the overclocking just fine, and I suppose it would do the voltage if the voltage wasn't locked on my gigabytes. I wonder if TRIXX might install in Linux with mono/wine? I'll try and post back.

To unlock the voltage, I'm considering updating the bios on the cards per this post: https://bitcointalk.org/index.php?topic=186624.40

But for now, I just want the miners to keep working through the night.

I'd love to move back to Linux, but I'm running 7970's.

I rely on Sapphire Trixx to overclock and undervolt. If the cg team could reverse engineer the undocumented calls Trixx was making I'd be laughing.

Actually, we don't need to rely on cgminer, an external tool would suffice - as Trixx does now. I'm surprised no one has put a bounty up for a linux tool for 7970 over/under clocking/volting.

I've concluded that Windows 7 Professional simply sucks. I'm using cgminer 3.0.0 on Linux Mint, and it has been running for four days without issue. My winblows machines are unreliable with cgminer 3.1.1, and have died many times in the same four days.

My ISP briefly cuts internet access almost every night around 1:30am, and cgminer doesn't like how winblows recovers. It's just a hiccup for linux. The bitminter client does better than cgminer on winblows when recovering from the interruption, but bitminter is not half the miner that cgminer is.

I'll be converting my winblows to linux. So far, that's the only solution I'm able to come up with.

Thanks for the great tool and support, ckolivas.

cgminer then locks up and becomes unresponsive.

All OK, except I had round-robin set, and I would have expected cgminer to roll back to the primary pool at some time? Perhaps round robin is only for the failover pools and does not include the primary pool?

ROUND ROBIN:
This strategy only moves from one pool to the next when the current one falls
idle and makes no attempt to move otherwise.
