I run a simple test of calling "bitcoin-cli getblocktemplate" in a loop. Normally this request is relative fast. But every 6 seconds it takes nearly 2 seconds to complete and causes 100% CPU load on a bitcoind thread during the 2 seconds. The bitcoind thread with the load changes each time so it is probably the bitcoind thread that happens to process the cli request.
I do not have time right now to profile bitcoind to isolate this issue. But I thought it was interesting that the requests take so long (busy waiting?) at nearly exact 6 second intervals.
I also continue to see bitcoind connection issues every hour or so. Connection is lost between 1 and 25 minutes! I need to make some time so I can debug the exact scenario. It occurs often enough.

Hi nonnakip, It's been nearly 12 hours since I implemented the bad IP block & I've had no bitcoind disconnects since doing so. I presume you've checked your logs for a similar repeat offender? Worth a try...... I just noticed Matt has released a new "dirty hack" relaynetworkclient for p2pool also - https://github.com/TheBlueMatt/RelayNodegonna try & compile it now & see if it helps any...... EDIT: Nope, it still won't run on 14.04 64bit - anyone else had any luck? |

Yes ... above 0.9.1 bitcoin core, RPC of Bitcoin Core (or bitcoind) crash because of the P2Pool server ...
It's not new.
I have an automated routine to restart Bitcoin Core every 30min~1h for this.
I'm pretty sure if p2pool was causing core to crash every 30 minutes to 1 hour, somebody would have reported it before now. I have never seen the behavior you describe, and I run p2pool servers on Ubuntu and OS X - sometimes for months on end without a restart of either bitcoind or p2pool. I also continue to see bitcoind connection issues every hour or so

Of course, the relay isn't actually responding to anything at this point... |

Anybody else have an issue connecting from a remote IP to the stats html pages?
It was working fine until last night, now all I get is garbled text with the only thing readable being the version number. This is when I connect from my android, no problems connecting locally however.

Yes, but with a system crash as soon as I started it...... Good news is I just compiled the latest release with only one warning & it's back up & running again The amount of received transaction sizes of 1347 & 906 is staggering though, & I don't seem to be sending any back at all - which I'm putting down to the attack I think. At least it's running again. Had my first bitcoind disconnect in nearly 20 hours a while ago too. Bummer. Back to the drawing board....... Edit: Plenty of this too: 127.0.0.1 Disconnect: failed to read message header (Transport endpoint is not connected)

So the original intent with the CoinCadence front end was to release the whole thing as open source... As sometimes happens in development, the whole thing became a complicated mess About a month ago I started working on a PHP interface to the Bitcoin API JSON-RPC with the hopes of it serving as the foundation for releasing the CoinCadence P2Pool front end, as well as about a hundred other projects I have in mind... It's not done yet, but with the TX volume spiking I wanted to release it, particularly so folks could have web based easy access to estimatefee and getmempoolinfo. There are 25 other commands supported in the Alpha, once I get them all integrated and the Chain Query source up on GitHub I'll re-work the CoinCadence front end to work with it and release that as well... Check it out: http://ChainQuery.com/bitcoin-apiBTC Talk thread: https://bitcointalk.org/index.php?topic=1115048.0Reddit Post: https://www.reddit.com/r/Bitcoin/comments/3cogxu/chain_query_alpha_a_web_based_interface_to_the/I hope you like it so far, any questions or feedback are welcome and appreciated. |

Great work windpath - well above my pay grade Been skipping around various p2pool node finders, there's still a massive amount of nodes still mining on outdated p2pool v13  I'm surprised there hasn't been a flood of complaints about missing payments from the last block....I'm seeing so many peers still getting banned......  |

Hi all, having some trouble with my p2pool node.
After the BTCGuild shutdown I decided to play my own game and run my own p2pool node. Got it up and running (Linux), bitcoind is running, miners are connecting and finding shares at the expected rate, but even after a week online I still get "Current Payout=0" and no payments to the address.
Quick help would be appreciated, because others might be connecting to my node and it's one thing to waste my own hash, but worse to waste someone else's. Thanks in advance.

What's your node address - I'll take a look. Also, whats your p2pool start up command? PM me if you prefer |

Wow BTCGuild a casualty of centralized pools. You are running 14.0. Whats you log look like when you run p2pool? |

Whats your hash rate? If your actually finding valid p2pool shares your "estimated payout" should reflect it immediately.... |

If you're looking at the default front end, the expected payout figure comes from the payout address of the node. When you setup p2pool, if you didn't specify one, a p2pool address was created for you in the bitcoind that it connects to. Unless you're mining to that address, your expected payout will always show 0. Take a look at windpath's node ( http://minefast.coincadence.com/miner.php) and enter your miner's address there. You'll see your expected payout, and what you've earned in any blocks that p2pool finds. |

How many GH/s connected ... thaht is the real question. P2Pool is a little more "serious" than Pools ... |

well, it's the point ... i run a win32 engine. Oh you poor, poor soul. Why would you torture yourself like that? I'm a damned soul. But, after rain comming the sun ... so, after 2 months of alienable search, i have found the solution for my problem (crash of Bitcoin Core because of the server activated) : an other program that it strictly survey bitcoin core process ... and restart immediatly. Now, it's work really well.  I'm happy (to mine with my own P2Pool node). program is : http://www.serverdoc.com/(alternate P2Pool french installation on Windows for everyone : https://bitcointalk.org/index.php?topic=1114415.0 ) |

Windows update did something (I think) and I can't figure it out (yet). While it doesn't effect my ability to mine or connect to the stats page locally I can can't connect remotely. All I get is garbled text then the error "the connection was rest".  It was working fine a few days ago, then my node started to get hammered by some sort of attack (made my S5 beep). I had some other users connecting to my node but they dropped off.. then the attack stopped. Then widows did an update and now remote connections are borked. EDIT: Win 10 is on it way in a couple of weeks, I'm not even going to muck with the works here... EDIT 2: Router decided to act up, I gave it the evil eye and it decided to behave. |
