The same problem happend to me. And I also got this

long poll: IO error

with the newest git version.

Its getting very anoying. I have to be restarting the computer like once or twice a day. I guess its time to change miner for me.

Very stable and great info from the console. Thanks!

I am getting:

Code:

[Miner0] bitcoinpool.com:8334 08/08/2011 01:18:44, long poll: IO error
[Miner0] bitcoinpool.com:8334 08/08/2011 01:18:46, LP connected to bitcoinpool.c
om:8334

about once a minute on bitcoinpool.com with the latest.  My hash rate is being reported by the pool at about 20% lower than it should be consistently.  This IS the only pool that has given this error though, but its annoying none the less.

Curiously enough, the last changes solved my problems. I have been now like 36 hours without a problem.

Try:

Code:

poclbm.exe http://lolo.1:[email protected]:8344 --device=0 -v 99 -f 7

The instructions are here: https://github.com/m0mchil/poclbm (scroll down to the end). You can now add a backup pool.

Its working... but something wrong

Can I use onlu GPU? 1 kernel on my athlon is using by 100%...
And second question - what is the best settings for my 5870 with using the backup deepbit server?

[RaTTuS]

poclbm.exe -d0 -v -w128 lolo.1:[email protected]:8344 lolo:[email protected]:8332
may help

[den11111]

No, empty fields still there

[RaTTuS]

^ I ment that is how you add a backup server
the blank lines are just the scroller - you cannot get rid of them ATM,

[spankymio]

Would you mind updating the windows executable please

Any one know any tweaks to keep pocbm from freezing up my pc when im using it i can mine for days if i dont use my pc but at random if im using my pc it will just lock up.  I know im running some high clocks on my gpus but its wierd only happens when i try to play a video or open a web browser sometimes im using a 5870@1100/600mhz and a 5970@940/500mhz.

hmm, there seems to be a bug in poclbm,

yesterday, me and some others experienced trouble mining with it. We were mining the solidcoin chain, and the problem seems to be difficulty-related(as soon as diff changed, things went back to normal). However, everytime the miner found a share, instead of submitting it, it put out a python stacktrace like this:

Is the exe still up to date and includes the latest kernel? Is 100% CPU usage problem still there?

phoenix miner works correctly (run w/ phatk2)

poclbm seems broken:

Check out the fix here:
https://github.com/m0mchil/poclbm/commit/3c4bf83c9fe8602c687afcd82d556cf58af4fbba

[m0mchil]

The problem is triggered by a feature in poclbm I suspect most of the users don't care at all - detecting if a real block is found if mining against a pool. The feature was introduced back in July 2011 and was fixed twice even before being released. Apparently, the fix was not good enough and with the last difficulty adjustment the problem showed up again.

I sincerely hope it is really fixed now. Latest github should be OK. I plan a windows binary release for today.
