Hi everyone I am getting the same error in cgminer in all of my rigs and it stops working
Error is the following:

Failed to convert header to data in gen_stratum_work

Any idea what this is?

That sort of error (not specifically that, but it's one possibility) would happen when you run out of ram... the question is why are you running out of ram.

Well it seems a bit impossible to run out of RAM (rigs have different configurations varying from 1gb to 4gb of ram). Could there be any other reason?
I don't know if it plays any role, all were mining at BTCGuild

Nope. It can only happen when it runs out of some kind of resource. It doesn't mean the machine itself ran out of ram, but the OS refused to give it any more.

Ok just noticed that this happened at the same time for all the rigs.
My best bet would be that it is the pool's fault, since it happened exactly at the same time.
Is there anything else I should look into though? Seems quite strange

I have issue about efficiency ...

U:9:02/m and U:5.02/m can i ignore it or worry?

thx

U: or Utility is how many shares per minute. Why would you ignore or worry about it? It's good information.

U: isn't very useful any more since the advent of higher difficulty shares.
If you mine at 2 diff only, then you'd double U: to get the equivalent 1 diff value.
However, you don't usually mine at only a single diff value ... it changes at least once when you start mining
(and on some pools it changes often)
WU: is way more useful in that respect ... however it includes rejects etc.

U: is still shares per minute. The WU: is a good estimation what you are being credited by the pool. In my case they are pretty close since all of my work is diff1. Still I think it's good information to have your rate at your fingertips.

I just have no idea what the OP was getting at so I was just attempting to explain what the U: meant.

FYI, for 3.1.0 on Win 7 64.

If one of many BFL units are unplugged cgminer will zombie that unit, if an additional device is unplugged then cgminer stops work completely on all units with usb comm errors.

I'm totally for keeping CGMiner as simple as possible. I actually wonder if one day you will drop GPU support for strictly ASIC support. However, the higher performance of native cuda seems to be pushing the cards into the realm of slightly profitable. A 580 seems to push 280KH/s, which is about $1.25/day profit.

I'm curious as to what miner this would be where they were able to get 280 out of it. As I'm one of those poor bastards trying to make just 1 BTC on my 670 with a profit of ~$0.30 - $0.50 a day

i can confirm this since i have a 580 too (slighty OC).
if your interested which miner it is, the miner is called cudaminer
also with cudaminer you only use RAM on your GPU, you dont need alot of sysRAM to mine it

my cudamminer uses 35kB RAM and allocates 1252 MB on my GPU (this depends on the launch-config of cudaminer)

Wait, is cudaminer bitcoin or litecoin based?

The answer to all your cudaminer questions: https://bitcointalksearch.org/topic/ann-cudaminer-ccminer-cuda-based-mining-applications-windowslinuxmacosx-167229

It's litecoin by the way, all scrypt coins actually

Kano,
I thought ASIC's were purpose built for Bitcoin mining. In the thread linked below this guy is saying people are mining Alt Coins with ASIC's. I was wondering if you had any insight on this? Can CGMiner mine Alt Coins with ASIC's?
Thanks,
Sam

https://bitcointalksearch.org/topic/m.2086549

cgminer can mine any double sha256 coin with the ASICs it supports (i.e. not scrypt coins like litecoin) and avalons have been used to terrorise some of those altcoins already.

OK, I had no idea. Thanks for the verification.

Seems i'm lucky for problems.
Got the message stratum connection was interrapted. Fine.. but why cgminer stay still and didn't switch to another pool (a have 2 pools in conf file)?

Well it looks like your using scrypt which I know nothing about.

Your using auto gpu which is good. I don't know if your engine range is OK?

Your not using auto fan so I would enable that and set the range for the fans to something like 60-85 instead of running at 100. Still seems odd that your GPU is even reaching 92. Are you running with your case on?

Since your not using auto fan and running them at 100% the only variable to control the temperature is to lower the engine clock and the floor is 800.

Something is missing.

Case is open, but cards i quite close to each other(no risers). So one of them is real hot, another one is 75 degrees.And the hot one ritching 90 degrees then cuting off by cgminer, and even when temperature low to target it shown 0 kh/s until reboot GPU thrue the menu.

That part is by design.

From the top post

Quote

If the temperature goes over the
cutoff limit (95 degrees by default), cgminer will completely disable the GPU
from mining and it will not be re-enabled unless manually done so.

But I'm saying that your GPU's shouldn't even be reaching the temp cutoff, so you need to work on that somehow.
