I had to do a git pull in p2pool folder and recompiled bitcoind from source to fix your problem.

Question for all of you - hoping for some help with this one.

Server keeps starting up, seeing shares, then crashing with this error:



Anyone had anything similar?
Currently in the middle of redownloading bitcoin 0.60 rc4 + blockchain + p2pool to see if I can fix it.

I've used pypy for a couple of days, it works ok, I don't see a big difference in CPU usage compared to python, but it has a problem: it is not compatible with pygame so you cannot show/generate graphs.

Bummer about both.  I don't use the graphs so hadn't noticed that pygame wasn't compatible.  But if it doesn't offer any significant CPU efficiency gain, it's probably irrelevant.
Unless you're running it on a system with restricted CPU power (like an ARM system) you shouldn't notice any difference (because p2pool uses so little CPU time on an x86 system as it is). That's why I recommended it to O_Shovah in the first place; because p2pool wasn't running fast enough with the standard Python implementation on his ARM system. I'm still curious if he's tried it out though, and if he notices any performance difference (ie., p2pool becoming usable).

I just upgraded to 6.0 rc4 and the most recent version of p2pool as shown on the first post, and am having issues. The error log is here: http://pastebin.com/3nga0nSB
Log was expanding rapidly, so I shut the node down.

Running on Server 2008 R2.

Seems your p2pool version is not current, so perhaps the first posting links to an obsolete build. Try to look a few pages back to get the link to a current p2pool build.

It's the latest tagged version from 16 days ago, and I went back several pages to no avail, because there do not seem to be any newer windows versions on previous pages.

The error messages you see are coming from bitcoin, not from p2pool.  Go make sure you actually have the latest version of bitcoin.  Based on what others have reported, it seems that the bitcoin installer often does not actually update old versions.  Maybe try the .zip file instead, or try uninstalling the old version first.
I used the zip, and I verified that I had downloaded rc4.

I don't know what to tell you to try next.  The error is coming from bitcoin when p2pool tries to ask it for the list of transactions to include in a block.  You need to figure out how to get bitcoind or bitcoin-qt happy again.  Only thing I can think of is to blow everything form bitcoin away (except your wallet.dat, if it contains any addresses you care about), and start clean with a freshly downloaded blockchain and a fresh install of the bitcoin binaries.

To anyone using my pool, I'm installing a Linux P2Pool currently and will have everything automatically changed over as long as you are using the domain name.
You won't have to change anything, as I will leave the other server up for as long as I can (so far the server has been online since 1/9/2012 10:11 AM EST since a reboot) that way your hash/s (shares) wont get messed up.

[Edit]: Currently downloading the blocks, shouldn't be too much longer.

Well you are right, my displayed version number is 1f87c32, too ... so that is okay. I use 0.6 RC4 on Win7, which works for me.
What seems weird is your error message "WARNING: Displayed transactions may not be correct!  You may need to upgrade, or other nodes may need to upgrade.". Are you sure your BC client is the 0.6 RC4? Are any errors in the debug.log of the BC client shown? Did you change the bitcoin.conf?

If you want to walk on water, get out of the boat
Are there known problems with the current p2pool build and the 0.6 RC4 build of the client? I got no share for quite some time, can be bad luck or an undiscovered problem.
I'll let it mine for some time and will report back ...

Dia
I have 0.6 RC4 and i find shares so it work fine

p2pool tries to use git to get its version number - no harm done if it can't.
I think you can look at '/path/to/p2pool/.git/ORIG_HEAD' to get the current version and then you don't need to use git.

Hmm:
Code:
cat .git/ORIG_HEAD
72d960a1000cb9ac97dc2eb3be33ace29f28dfd5

whereas p2pool does:
Code:
git describe --always --dirty
0.9.2-59-g6b4c15a

Nope, you can't...
Hmm. I didn't realize that it got the version number too. I thought it was just the commit hash.

Code:
$ cat .git/HEAD
ref: refs/heads/master

$ cat .git/refs/heads/master
6b4c15aeae4604ef3c536ea2cc695ae2be160914

$ git describe --always --dirty
0.9.2-59-g6b4c15a

I just downloaded the latest code from github.
This is what happens when I start p2pool:

Strange problem with my P2Pool node.
Everything was running fine, hashrate about 1600Mh/s (600Mh/s of my own hashpower + 1Gh/s of unknown other miners I assume).
I go away for two hours, come back and it takes 20 minutes (!!!) to establish a remote desktop connection to my server. Finally get on and the p2pool window is scrolling so fast I can't read anything, whole system is almost completely unresponsive. Memory usage is about 140MB and CPU Usage is 100%.

Hard reboot vpn, find that bitcoind now refuses to connect.
Have now switched over to 0.5.3.1 and reinstalled everything and p2pool is working again, stable with 2% CPU load and 105MB of memory in use.
Any thoughts?

What does the p2pool log say for the time that it was broken?  Hard to diagnose without knowing that.  The log is kept in the data/bitcoin/log file under the folder where p2pool is installed, so you can go back and look at it after the fact if you didn't delete it when you reinstalled p2pool.
Haven't got the logs grabbed off the server yet, but it happened again, node hashrate grew from ~1100Mhash/s on the restart to ~2Gh/s over the course of a few hours (that time ~850Mhash of my stuff, plus whoever's directing shares my way), then this happened:

Huh

Running RC4 without problems for 8+ hours. Everything looks normal.

Still no share, what is your hash-rate?

Dia

Dia, I had a day like that the other day.   Ended up with a few big gaps with no shares.  Try a reboot, and a git pull on p2pool.  I just updated bitcoind to rc4 myself yesterday, everything seems pretty normal.  With 2.3GH/s I get about .40 payout.


--edit---
Oops, sorry I actually am using rc3 in linux.
