Any other input on this? If shares are being dropped early, it seems like this is either a bug that is causing it or a bug that is being exploited by a malicious actor (?). Either way, not good. I'm willing to help with diagnosing this if anyone who knows what they're doing is interested. I suspect it's easy enough to duplicate.
I'm pretty sure it's not a p2pool issue, otherwise we'd all be suffering from it? So, that leaves either a malicious 3rd party or it's a problem with the users setup. My diagnostic skills are fairly limited I'm afraid - so I won't be much help. If it were me who was having this problem, I'd consider ensuring my rig has all the right security settings set up correctly first (firewall, ports, iptables etc), then I'd start from scratch & check all my configs, redownload/recompile everything & see if the issue persists. Not very helpful or fun to do, I know - but that's what I'd do....... ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif)

Once those shares are in the p2pool net, it shouldn't matter my setup. Personally, I'm a casual miner and this has only cost me a couple of $ worth of Bitcoin so I'm not going to sweat it too much unless it keeps happening but I'm willing to give back in terms of assisting troubleshooting.

@ windpath: Are the luck stats displayed on your web GUI correct?:
They are not 100% accurate, but about as good as we can get with the data available. The global hashrate reported by any p2pool node is an estimate based on difficulty and submitted shares pool wide, so expected time to block is not perfect. If you dig back in the thread when I was developing the front end I published the formula used and how it was calculated for feedback and made some tweaks. If they are, I'm pretty sure there isn't another pool out there that can touch us atm ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) I agree 100%. Even when our luck is down I still think P2Pool is by far the best option for miners. - Trustless & Decentralized - Highly resistant to DDOS attacks - 100% Uptime if p2pool backup nodes are used (best use for my node) - Lowest orphan rate of any pool, period. - Open source - No registration of any kind - I could go on and on, but I think you get it already ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) On the mempool monitoring, it has grown to 11.5MB overnight, nothing to be overly concerned about yet, but will continue to keep an eye on it. bitcoin-cli getmempoolinfo { "size" : 6090, "bytes" : 11401452 }

... I watched as the bitcoind would slowly consume more and more memory, up until it took almost the entire 8G available, at which point it would invariably die off.
What was the magic you used to produce the output, (8G <-- bitcoind is using this much ram.) Somethings not right there man. Linux will try to use alot of the computers memory to keep the system fast. 8 gigs of ram i'm thinking is below average for power linux users. Is adding more of it an option for you. Maybe i'll bootstrap a build and run the latest bitcoind and the p2pool to see what the story is. No magic at all... and honestly I'm not sure why things just kept spiraling up like they did. I had that node running for over a year and never experienced any problems with it until relatively recently. I ended up just killing the node. I couldn't justify the $80 a month expense, and I didn't have the time to constantly monitor it to ensure it was behaving. I know there are plenty of other nodes out there running on Linux, and likely not experiencing anything near what I saw, and to be honest I never bothered inspecting it too closely. I just finally got fed up with the hassle and realized that I didn't want to deal with it any longer. I still run my own local node and now use windpath's node as my backup instead of my own VPS.

No, this is not the right metric. The cases I've seen of bloated memory usage have been from something other than the mempool itself. My nodes typically have 2+ GB memory usage ("RSS") after a few days, but only 0.5 to 20 MB of mempool usage. You want to check the RSS using a program like top, or check /proc/$PID/status (Linux).

Hmmm, took a look, your right, at 2.5GB. Will have to investigate further tomorrow.

not that difficult to estimate ... if you are the only one running p2p with 2.3 PH then you would get all 25 btc rite ? so now p2p is around 1.7ph + 2.3ph (yours) = 4 ph math comes out to a little over 13 btc NOT daily. it is ONLY when p2p hits a block or more then you'll be rewarded with the btc which could be 4 a day too. oh you do get a little "extra" bonus of 0.5% if you're the block finder. i'd say give it a shot but you'll need lots of patience in p2p but it does pays off. ask away as many here would be able to give you answers to p2p.

Maybe. I don't know enough about it. I would imagine that p2pool talking to bitcoind is simple enough that simple load balancing would be enough but I don't know enough to say for sure. I have found crossroads as a load balancer possible able to do this work. I am going soon to test running two bitcoind with two independent internet connections and let my p2pool node to be connected to them over crossroads.

If you have 2.3PHs you will get daily 13 BTC. Actual luck is higher than 100%. 30 days luck is 147%. So ideal calculacion is 13*1.47=19.21BTC. My own 42 days back statistics says I have got around 120% of what I could mine with other pools. But for to reach this you need to have well done p2pool node (great hardware), well done bitcoind server, great internet connection, well tunned miners (spondoolies do not need any tunning, antminers do). good luck

You can't use historical luck to determine future payout - that either ignorance of mathematics or deception.
Also the p2pool luck is over estimated by most sites coz it includes extra blocks but not the hashes that mined them - so yeah blocks with zero hashes will of course fake the luck up higher than it really is. (The stale p2pool blocks that are valid blockchain blocks have no hash rate counted towards them in most stats anywhere)

I'd rather NOT to over estimate the payout using history for future payout but use the history as payout reference/estimation based on a worse case scenario. just my 2 cents. don't really need a good hw but of course it is preferred. maybe the correct term or word is "Proper Setup" hey but that's the fun of learning ![Wink](https://bitcointalk.org/Smileys/default/wink.gif) -bitcoind is bitcoind, i'm using qt on win7 & so far so good. -great internet connection ? i'd say STABLE no need to be high speed or high bandwidth -tuned miners ... hmm preferred of course but ant's do run fine some miners are NOT compatible though but should run. ask away & you shall get answers. imho, there is no 1 single pool that's the best. all of it has it's up's & downs. be your own judge.

OK, think I'm done with this pool. My payout on the last block according to the graph should have been 0.012 but was actually around 0.005. Then I had to restart the pool and bitcoind and my shares dropped again. Something screwy, chaps.

I'm not sure what front end your running, but the predicted payout reported by p2pool is exact if a block is found "now". Perhaps you had some shares drop off from when you saw it and when the block was mined?
