That's looking better, even though it is early doors. How did you manage to get connected to so many peers (30 &24 in)? I've never managed to get above 11 & 0 in.....

That's 6 outgoing (which is the recently revised default) and those always fill up quickly.  The incoming ones always take a few hours to re-arrive after I restart p2pool.  The only way another node will connect to me is if it is restarted, itself (and therefore needs to re-establish it's 6 outgoing connections) or if it loses one of its 6 outgoing connections.  Also, nodes prefer to connect to "old" peers that have been around for a long time, and my node has been running consistently for about a year, so I don't usually have to wait more than a day to be full on incoming connections again.

Was I helpful?  1TwmzX1wBxNF2qtAJRhdKmi2WyLZ5VHRs

i changed the code to create 30 outgoing connections, its fairly easy!

There is a reason it has a low default and is limited to 10: Outgoing connections are a limited resource, since few nodes are set up to accept incoming connections. See the discussion of the "Hub" patch to Bitcoin. Tongue

Besides that, you don't need that many connections. Bandwidth usage scales linearly with number of connections, but the benefit of increased connections on your orphan rate is small.

so we hit the halving. and p2pool thinks the next block is worth 38.55495555 BTC

there's not a chance in hell there's 13.5btc in transaction fees.

Actually there is  Grin Look: https://blockchain.info/block-height/210000
Transaction Fees    13.56295554 BTC
It was planned action (by Twitters), for 210000 block to be remembered in history Wink

Well.. after about 24 hours, the new version isn't helping me any.  I still get 5-10% rejects from cgminer, and 25% stale/dead from p2pool.  Maybe stratum will help.

Latest git 9.1-9-gb246991 works much better for me.
Memory usage on linux finally drop to around 500MB, no doas.

OK, after 18 hours uptime I can't see any significant change - still at 25%+ orphan/dead rate with large memory usage. I have also noticed a lot of the "tx" comments in the logs, as well as the "punishing share for stale" thing - whats with that? Even with the high stale rate I notice we're still getting payouts on blocks (albeit lower since halving) so it's not all bad, although I find myself wondering what the payouts would be with a normal reject/orphaned/dead rate...... Sad

Right, just switched over to the newest git from Rav3n's skydrive - thanks for the heads up Rav3n. Lets see how this baby goes......

Is there a way to see the git version when you download as zip?  once upon a time it was in the filenname, now everything is "p2pool-master".

mdude,

the best way is to issue a git clone the first time and then, cd into p2pool directory and issue a git pull when you need a new version.

you have to install git, but from then on it will update itself seamlessly.

He meant windows.
I not see how it ca be done automagically.
I`m doing it by gitpulling on linux, see version number then compiling windows version using that data.

rav3n_pl,

sorry, I'm using linux only on my rigs.

You can run python and git on windows, though, so it should work (at least in theory).

Well, after only being up for a few hours with this latest release I can already see a 200% improvement - 10 shares - 0 stales - 0 dead. Now THATS more like it, back to normal again, so far. What ever changes were implemented in this version seem to have worked wonders for my set up at least. Noticed some more additions to the logs that I've not seen before:

KNOWN: 141425
MINING: 60749

It's showing often, can someone explain these? I presume it's some kind of checking that has helped eliminate the bad shares?

Just installed git for windowz ;]
Code:
C:\msysgit\git\p2pool>run_p2pool.py --version
b016b6b

Sadly it is not showing full version, only git hash :/
Same after compilation to exe.
Looks like "manual" way is only way for dat windowz to show full version number.

With the block halving, my profit is gone, and I had to shut down my miner. I still have Bitcoin-qt and P2Pool running, thinking having a full node available will help other P2Pool users somewhat (have about 24 incoming connections). Someone let me know if I'm wrong about this?

forrestv: Much better latest git master after 6.5 hours.
Version: 9.1-5-gb016b6b Node uptime: 0.415 days Peers: 10 out, 24 in
Shares: 89 total (5 orphaned, 3 dead) Efficiency: 121.9%
Still got 27 Get Fails in that 6.5 hours, but no Rem Fails.
2.9% Rejects which is also much better.  Smiley

Edit:
htop at start showed 485M RES and 636M VIRT
htop after 6.5 hours  622M RES and 775M VIRT

Watching for 5 minutes I never saw CPU go over 56% Most of the time it is 20 or lower.

Still need to figure out why we get so many Get Fails. I know it is not hardware. I have a really fast server (lots of RAM, 8 CPU cores, and 16TB free space on Hardware Raid 6 ) and a fast Internet connection.

I got 2 Get Fails on solo with bitcoind in 24 hours for comparison.

I have two subnets.
Each subnet running bitcoind, but wallet.dat used in both cases is the same.
Also in each subnet running p2pool.
Can I setup two subnets are the same address for the award?
Are there problems?
