Well when recoding p2pool, It would be Nice to solve the "payload too long" issue as well.

Does somebody know how to deal with this?  Huh  

Please check this post: https://bitcointalk.org/index.php?topic=18313.msg10164796#msg10164796

 Roll Eyes

So doing some digging, the "payload too long" error comes about when a packet's length is greater than max_payload_length.  This can be seen in p2pool/util/p2protocol.py.

This is called from p2pool/bitcoin/p2p.py and p2pool/p2p.py where it sets max_payload_length to 1,000,000.

I am going to change the code to print out the packet size, as well as, change the max_payload_length to twice the size.  I will let the code run for awhile and see what happens and report back.


If I'm correct the 'maxblocksize' is hardcoded to 1MB into the Bitcoin protocol. So I guess changing the payload length does do the trick within P2Pool code (until the blocksize will be increased). Well it is still unclear to me what part of the code you have changed. Logically it had to do with Bitcoin Core which is responsible for "packaging" the block and verify the hash of it. It would be awesome if you still could update us with news. I've also updated my Bitcoin Core and I'm waiting for a long blocktime with lots of transactions to debug my new setup. So, I'll keep you guys posted! Thanks!



Yes, the block should not be coming into p2pool over 1,000,000 or perhaps it is sometimes coming in with a size of 1,024,000 (another meaning of MB).  Or perhaps p2pool or bitcoind is somehow corrupting it at certain times which is causing this issue.  We'll see and my logging should let us know a little better what is happening.

I see you're using an Rc version: v99900 - Maybe that's what's causing your errors. I only use the stable release versions for mining.......

OMG, Why I didn't saw that myself?  Embarrassed
I'm gonna deploy a stable release of Bitcoin Core to factor this out! Thanks!

I've been monitoring my P2Pool Node very closely since the update to the last Bitcoin Core version. I found out with Block #339.597 (which took about 50mins and had more than 2000tx did not grow beyond the the maxblocksize of 1.000.000! This is great news now the P2Pool did not gave any "playload too long" error at console. The update to a later Bitcoin Core did the trick. I would advise everyone to update their Bitcoin Core concerning this issue!

Thanks for the good help and your efforts everyone!!!

be aware that the maxsize for a tx is 50kB. unfortunately hardcoded...

No kidding! 3rd time is a charm....

Edit: Double checked to see if it was a record, that's our 2nd luckiest block since I've been tracking at %70,579 Smiley

First place is still block 329431 at %180,136 (just 30 seconds after our previous block)

Really hard to find a better pool than P2POOL, it lags and some poor equipment doesnt work with it but then in the end those broken s4:s doesnt work anywhere else either  Tongue

All I ask is someone to make the tool for donation, so we can donate who ever we will --donante % --addres

I dont think Forrest is against it, because it seems he has better plans than P2pool at the moment? If im wrong then im wrong. Just hope that P2pool can grow up a cow.

I wrote a widget called p2poolwidget for android a while back.  I think if you search for p2pool in the google play store it's still the only relevant app you'll find, sadly.  Anyway, I wrote it back when I was mining, which I haven't been doing in a long time, just so I could monitor my setup.  I was trying to learn android programming at the time, so the code is pretty sloppy.  I'd planned to try to improve it over time, but then mining on p2pool started becoming less and less rewarding and mining in general became unprofitable for me soon after, and I just lost interest basically.

So, I haven't made any updates in quite a while.  Then someone emailed me a few weeks ago asking for some changes, and I told them I didn't really have time, and they asked if I would consider open sourcing it.  So I put it up on github a couple of weeks ago.  I was going to wait until they confirmed they were able to get the code to compile, but I'm pretty sure it's all there (if not, sorry, it's first time using github).  So, basically I thought I'd mention it here in case any one in this thread wants to make their own changes.  You should be able to get to it here: https://github.com/ksenter/P2PoolWidget

If you want to release your own version, just give me credit for any of the code, or ideas, of mine that you keep.  Other than that, have at it.  Good luck!

Set them all to use queue size of 1.  The easiest way to do that, but it's not permanent, is to SSH into them and enter:

/usr/bin/cgminer-api "setconfig|queue,1"

That will be lost when the miner reboots or you change your pool config via the UI.

Yes and no. Sad

S1s and S3s are finicky about this.  S2s and S4s should accept the command without a problem.

I don't remember how to get S1s and S3s changed.  Maybe someone else can chime in?
