Money is the root of all evil.

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.

Thanks man, your effort is appreciated..

Can a pro show us noobs how to implement the fix? I'd be happy to throw a coin or two someones way for a quick tutorial on getting it back working correctly.

You can see in BOLD, pull from git if you are Linux user, wait if you are windows user for binary release.

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

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:

Help me please.
I'm download the latest version, but it's dont work with old configures...
start poclbm.exe --host=arsbitcoin.com --port=8344 --user=lolo.1 --pass=lolopass --device=0 -v 99 -f 7
I use win7 32bit
What's wrong?

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.
