Yes, my post is from after 0.9, I installed it last night right after the email went out. It has happened twice today, once when I saw all my shares go orphan and other time they didn't. How does something like this happen? Not that I claim to know much about how this all works but, to me, it doesn't seem like it should be possible that P2Pool gets confused, I get 10% of what my payout should be then I restart and it goes back to normal.. Where did the extra coins go?

Ah, sorry. I thought you meant in your first post that you hadn't seen the problem with 0.9 yet. Looking into it now.

There was a fix for behavior this in the most recent release, 0.9. Litecoin's blocks are 4x as fast as Bitcoins, but P2Pool cached the last 1000 shares regardless of which blockchain you were mining on, and chose the wrong chain if the block headers from 24 hours ago weren't known. However, if you still have problems, please do tell me.

I honestly don't care all that much since it's Litecoin, which are borderline worthless and getting worse by the day. I guess it just makes me worry fundamentally about P2Pool if my work can disappear this quickly. Could work be faked just as easily?

Having a Litecoin mining problem. Usually when a mined block comes in, I get little over 1LTC but a few times a day, the transaction randomly comes in at .3 or .2, something like that. About 50% of the time, I see that all my shares in P2Pool go instantly from normal to orphaned eg: 125 (8 orphan, 1 dead) to 125 (124 orphan, 1 dead) which drops my payout down to a fraction of what it should be. If I reset P2Pool, my shares go back to normal and resume normal payouts.

I'm having problems with LTC p2pool mining too now after updating to latest version,for some reason when i start minerd my hashrate in cgminer plummets by about 50%.

This doesn't sound like it could be P2Pool's fault... Try Litecoin mining with less threads so cgminer has some cpu headroom?

Now in this case, my shares didn't go orphan but I still got the random low payout. Also, as you can see in P2Pool my payout should have been 1.2LTC for that block. P2Pool is the most recent version JUST released but I was having the problem with previous versions and I do not have this problem with Bitcoin P2Pool.

Thoughts? Suggestions? Criticisms?

So I'd also appreciate some help!

I have read the wiki but still do not understand how I get namecoins as well as bitcoins with this pool. What do I do to get namecoins?

Setup namecoind with "server=1" in the conf and add "--merged " to your run_p2pool.py command. What more do you need to know?

mine them solo. p2pool is bitcoin only however you can solo mine NMC at the same time via merged mining. There is no sharing of hashpower, blocks, or rewards for NMC though.

seems the p2pool HASHRATE stop growing ?
what's wrong? full?

Anybody running an old version is going to have p2pool stop working. That's going to affect the hashrate until everyone upgrades.

Yeah c'mon you slackers! Hurry up and upgrade you're slowin' me down!

Variance.
As hashrate goes up block variance goes down.
As hashrate goes up share variance goes up.

This is a non-issue for large miners but for small miners large share variance can be discouraging. Waiting 2 hours for a share only to have it end up orphaned and payout = 0.0 can be rough. I think in the medium term p2pool can grow by encouraging small pools to use p2pool as a backbone to reduce variance.

Longer term something needs to be done to help smaller miners w/ share variance. There are a couple of potential solutions. Personally (unless forrestv can school my on any misconceptions) I think p2pool evolving to be a high difficulty backbone with longer timespan between shares supporting large miners, "subp2pools" and conventional pools is the most ambitious but also most comprehensive solution. It could scale to support a significant fraction of Bitcoin total hashing power.

Unable to mine on the latest p2pool with ufasoft .28. No error message given, just sits at 0 KHash/second. Anyone else having a problem like that?

What was the last version of P2Pool that worked?

We performed 114% better than PPS pool, at least in last week(even with a 1day 7hours long block). Grin

And the next week it might be the other way round.

It's called variance Cool

New cgminer version 2.2.7 designed to cope better with failover circumstances involving p2pool as it effectively works off a different blockchain.

Let miners voluntarily raise their share difficulty so P2Pool's required difficulty can drop, which will lower variance for small miners

Sounds great. How does this work?
