ME? Improper? Who wrote that script??? ME?
Anyone who use it will NOT support forrestv by this nice automatic feature.
As said in my original post on this subject this script is tailored for my needs and meant to be edited for p2pcoin's needs. Wasn't it clear enough? Should I have use the troll language, using capslock and several interrogation points?

P2pool tuning guide
Trade BTC for €/$ at bitcoin.de (referral), it's cheaper and faster (acts as escrow and lets the buyers do bank transfers).

Lol, if I was in your place I`ll just not paste things like that... Nice idea for a startup/cron anyway Smiley

Ok, someone tell me how THIS is possible:

Code:
Blocks found in last day:

Note that blocks may have been orphaned from the P2Pool chain and so not be here.

Looks like he mined a totally junk block, perhaps due to his bad connection or his bitcoind misbehaving.

Junk shares like that shouldn't be accepted, they should be orphaned. Perhaps similarly to the discouraging Gavin implemented for bitcoin. Hopefully the devs will fix it soon! Smiley Edit: this is already what is happening, there's just a special rule for block solving shares, that's why it got through.

Indeed if you explore his shares around this incident you'll see he was having a very high orphan rate. The pool orphan rate spike are mostly all his shares, it seems. In the end, p2pool was not paying him, urging him to fix the problem.

Rav3n_pl forwarded me a link to his local p2Pool stats page, which was very useful.

Can anyone else do that? Or take a screenshot or something? You can pm me the screenshot so it wont end up public.


Useful with just one person on it?  Well, have a gander at http://5.9.24.81:9332/static/     if you like

my payout has been steadily decreasing, i think i should have stopped at max and went back to maxbtc,  then wait til all my shares expire to come back  *scratch*

I obeserved today a phenomenon

Suddenly my stales rate went drasticaly up allso the whole machine was lagging badly, im not sure about what did cause that, i could not find any activities in my logs so that wasnt caused by any apache related activity, just p2pool and the chains was running. I suspect that this has something to do with peers; this could be intentionaly or cause of a bug. i realized that stales and orphaned shares on the p2pool operating chain are probably caused trough this.

The solution is simple: restart the pool more often, a node that is running to long probably causes a higher amout of stales or even orphans...

investigated that my ztex-boards caused the problem. for some reason java took 100% of all 4 cores.
did a reboot and every thing is fine now.

I would llike to point your attention towards the BMP Project listed on cryptostocks echange. This project has as the one of the primary goal to add a nice amout of hashpower (acutaly approxmatly 30 gh/s on avarage) to p2pool. At the moment the shares are free to buy in total 50k for a price of 0.1 BTC each. I would realy feel honored if members of the p2pool comunity would deside to become a shareholder. For more Informations please visit https://bitcointalk.org/index.php?topic=90880 or directly at croyptostocks https://cryptostocks.com/securities/9 . For Security concerns: My personalities was audited and verfied trough cryptostocks https://bitcointalk.org/index.php?topic=88036.20

Did this per chance happen at midnight 12 AM on the 1st of July? There was a leap second adjustment that has caused all kinds of problems. The solution is to reboot the computer that is having issues. This max CPU usage is something I have heard developers in other non Bitcoin related IRC channels mention.

So I realize it hasn't been very long, but have the new share changes helped the orphan rate?

yes, it happened at 12AM and it was caused by the leap-second. I read that bitlc.net had some trouble with their java-apps too.

Yes! So far v3 changes have helped to save 1 block from being orphaned.

Still quite a lot of orphans past few days, hopefully it's just bad luck - they were all close calls.

Sadly, people running outdated clients are almost certainly not reading this thread.  Pretty much the only way to get their attention is to force an upgrade (i.e. fork them so that they stop getting paid regularly).

https://en.bitcoin.it/wiki/P2Pool#Miners
Added simple tips that help few ppl reduce local DOA when using cgminer (best miner imo).

We have 2 kind of stales/doa there.

1. Miner getting work from p2pool
2. Miner finds a share diff>1 solution and send it to pool
3. Pool register share to calculate hash speed of miner
4. Pool checking that SD of share is higher that current SD of p2pool
5. If 4 is true Pool sending share to to other nodes.

Tuning miner options can reduce DOA that appears between 2 and 3. We can see it as red line in local graph.
It will NOT reduce doa/stales in between 4 and 5. Forrestv is struggling to improve logic of pool in that point. BUT like in "real" bitcoin share chain there is no way to reduce number of orphans to 0... ;]
