And we have liftoff people, block has been solved.
I'm now interested, what caused this?

Anyone else having wallet sync issues?
Lots of sync issues... Started with block 78414 and continued with most of the succeeding blocks (until 78421 which is the "current" block of my most actual miner). Seems to be related to the size which is > 200k |

Miners pulled out?
No. My logfile shows a drastic decline of PPS over the last 45 minutes or so. Plus there's a lot of transactions somewhere. I think we've has slow blocks before, but not *that* slow. Would be interesting to know if this was a glitch or a deliberate attack... |

Is everyone here using mikaelh's build?
I haven't tested Sunny's yet but with mikaelh's, my PPS stays at about 100% (~600) for about an hour or so, then rapidly drops down to 10% (~60).
I'll switch one of my miners over to Sunny's build and see if the problem gets solved.
If this bug affects everyone, it could explain why the PPS dropped so much.

Anyone have that issue, check your currentblocksize, it's too big. |

Anyone have that issue, check your currentblocksize, it's too big. It's at 202233 right now. Didn't know blocksize affected PPS but I guess that could explain why. |

All of my miners were showing much lower primespersec values. I restarted all but one. After letting them warm up again, I noticed that the more recently restarted ones had 0 or 1 currentblocktx and a small currentblocksize, and the still slow miner had currentblocktx 9 and currentblocksize > 70000. Now a few minutes later, all of my miners are slow again and back at that point. Maybe those pending transactions contain some sort of denial-of-service attack? (Or maybe they're just unusual but legitimate and the client chokes on them.)

Seems like it. Jesus blocksize for 78,424 is 202,878 and there are 19 tx. The block 78414 was listed as having over 10 tx but there is only 1 showing up in the block explorer. Strange... |

I'm at 78425.Derp, I forgot how to math. 78425 > 78242. |

Looks like the bad transactions are still coming in.
Couple of examples that look like the culprits:

Strange... block 78,242? I'm at 78425. Sorry, block 78,424. It was a typo. http://primecoin.21stcenturymoneytalk.org/index.php?block_hash=500caad077bcc16b2d92141b46bffe28f17206b5a7d067d2ae9b897391a10495Definitely something strange going on. Blocksize is only 208 and there are no transactions. They were pushed back to block 78,425 |

The block explorer is still probably a bit buggy in some places. If it's correct for this bit, then someone is sending transactions to transfer batches of 10k XPM.

Probably a big miner getting ready for his dump. I'm already seeing 14k+ dumps on mcxnow.com |

Those transactions have of hundreds of inputs, but is that really supposed to be an issue? Does bitcoin handle large transactions like this? Maybe primecoin is doing something like accidentally hashing the whole block repeatedly somewhere it shouldn't during mining. |

Either someone is moving some epic volume or the network is being attacked to cause panic sells. |

Panic selling at mcxnow.com.... Wonder what those miners with 100K+ PPS are gonna do now. haha  Same thing I am. Wait a few hours for it to sort itself out. |

Some weird stuff going on, weird block delays. What if we've hit the boundry between what the network can handle, and what the difficulty expects us to handle, and that's why we are flip flopping between mining and waiting.

A few really large transactions seem to be causing performance issues with mining for some reason. |

It is not an attack. It's an issue in the miner that doesn't handle large block efficiently. A fix is being tested. Both the stock miner and mikaelh's miner are impacted.

I tried taking the creation of a new block template outside of the loop, and it still seems to be affecting me. |
