Hi guys, do you have any idea what might be causing this hashrate drops on my p2pool ?

http://freebtc.eu:8336/static/

I was going to guess no internet until you posted the error log.

"0197 > Failure: twisted.internet.error.ConnectBindError: Couldn't bind: 24: Too many open files."
 suggest you should look into raising the number of file descriptors. Have not run into that problem myself yet.

Part of the problem may be that python is an interpreted, not compiled language.

I have seen compiled versions of p2pool (at least for windows in the OP). Anyone have instructions on how to do so? I'm not so much interested in increasing the performance as making it easier for others to use without having to load dependencies.

I got an error where it said something about trying to broadcast a share without having all the transactions (?). Then the share was counted against orphans, I think. The message scrolled off before I could save it. There's no log file for p2pool right? At least I couldn't find it.

It's in data/coinname/log

I've put in a pull request to fix the problem with vardiff sending out 0 diff work that causes some GPU miners to spew endless HWs.

Has anyone ever seen their P2Pool show "no shares yet" under the Active Miners on This Node?

I am seeing this on my Bitcoin P2Pool, also I am seeing the entire pool hashrate has dropped steeply to 99TH/s.

It's possible the local and global hash rate figures on web interface are being averaged over different lengths of time.

Have a look at my node; http://p2pool.smoothrunnings.ca:9332/

My local hardware is which the top one is not showing any shares, it was even doing that before it took it down for a while today; I had another issue both with my bicoind (bitcoin-qt) and my own wallet; that issue is I transferred just over 1/2 a bitcoin out and it got stuck. So after a week it according to my personal wallet started to get peers (3 of 6 now), yet on my node it still shows 0 confirmations. Anyhow even after putting my node back up and its been a few hours the miner on the bottom which is running from a different location is getting shares.

The difference here is that the two inside miners have been updated to cgminer 4.0.1 while the outside miner uses 3.9.0 I wonder if the 4.0.1 cgminer is causing the "no shares yet" issue, if it's an issue?

What do you think?

Thanks,

now your node shows 2 shares. considering your uptime it is ok.  both shares are probably made by your miner 1JiWFoe6QaE7N6mv2HBkjr4izuDX3cqDQQ. little patience and i think all will be ok.
it can be that both miners made one share and because you have 50%fee one of the shares is going to your node wallet. as you can see your node is "earning" more than your miners.
as far i cold notice there is no differences which version cgminer you have, results are practically equal. my miner with 4.0.1 work fine and i don´t see any difference to miners with 3.9.0.

Enjoy your life!

okay I will wait a bit longer to see what happen, but it used to never to this, both miners always showed  predicted payouts. On a different note the p2pool-note-status static page has been updated, it now shows the "payout if block were found now".

"Predicted payouts" is misleading because it sounds like you will be getting a payout. It's actually just the total value of your shares in the share chain at that moment, same as if you click on Payouts on the Extended interface. If a block it paid out right then, that's the amount you'd get paid, because that is your total share value in the share chain. It doesn't mean the pool will find a block (you might get paid zero). The pool could also find many blocks (you'd get paid that for each of them).

On my nodes I've changed it to say "Your Share(s)", hoping it's more intuitive that way.

Are there any benefits/limitations/issues with using alternative blockchain daemons with a p2pool node instead of the standard bitcoind/Bitcoin-qt?

I'm currently using the Bitcoin-qt OMG client with wallet disabled.

Was thinking along the lines of btcd which is currently in alpha or some other optimized client.

Will restart all my nodes one by one to make it happen.

ah, nice, just noticed this

i'll probably start up the doge pool again

ah, long live doge, too boring to monitor all the new shitcoins, just leave it on there for a month or so

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).
