cgminer "stratum connection to pool 0 interrupted" issue

[Fluxbit]

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.

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?

[Andrey]

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!

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

[Andrey]

Thank you! Will report if problem still persists.

i have the same problem as u guys here.. keep getting stratum connection interupted error, ive tried cgminer 3.2.1, 3.1.0, 3.1.1... they giving me same problem.

[superresistant]

same here

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.

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 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.

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 haven't found cgminer dead in the water for some time now, but cgwatcher has restarted one rig a couple times a day due to 'no new shares submitted for x minutes'.  I can't say if that's stratum interrupt, or some other issue, but I don't care with cgwatcher babysitting.

Thanks for the updated software, ck!

It happens to me sometimes with rigs on the same network. It will say "... interrupted" and never reconnect but other miners are fine and never disconnected in the first place so the pool isn't the issue. Sometimes it reconnects but lately it hasn't.

Trying to figure out how to get around this atm...

Good summary of what I'm experiencing.  I'd only add that two win7 rigs on the same hub as a linux rig, the win7s puke often.  The linux rig is a rock.

What sucks is that cgwatcher doesn't catch this.  Often I will head to bed at like 1am and wake up in the morning to see that the last activity in cgminer is interrupted at 1:45am.  You can still ping it, you can still vnc into it.  Not sure how I can detect there is a problem other than a managed pool that emails you when it hasn't received shares in awhile.

Have you tried the 'restart cgminer if shares haven't changed in 10 minutes'?  Works for me--at least in the context you've described, at a high level.  Good luck...

Same problem and same solution as you.

Using cgminer 3.3.1 on Windows 7 x64. "Lost xx shares due to stratum disconnect" and cgminer never recovers from it. Note, that only happens sometimes, at other times it will go to the failover pool.

Cgwatcher fails at monitoring the drop in hash rate (the cgminer window still shows the last value before the disconnect), however "restart cgminer if shares haven't changed in x minutes" works just fine.

[rwessels]

I completely missed that option.  I am setting it now and hope that works.
