[ANN][YAC][POOL]p2pool for yacoin!!

[caish5]

I'm using the new one.
Mainly because I didn't like the error displayed by the old one, but I'm pretty sure they both work fine.

any ideas?

[caish5]

I have the same thing, but I'm no p2pool expert.
rav3n_pl is probably the guy to ask he has a similar problem in the main p2pool thread.
The problem there seems to be an update to bitcoind, but in our case I'd say I caused it with my changes.

On the other hand the pool does appear to work ok and pay ok.

[caish5]

Actually more reading suggests the problem may be connecting with stratum instead of longpoll (Is there a hacked cgminer that does scrypt jane?)
If so a --fix-protocol on the miner's end may solve the problem.

[eule]

Thanks a lot for this, it was really necessary.  
These errors had me worried too but payouts work fine. Tried running this on another (more powerful) server of me on Debian 7 but i get "version glibc_2.14' not found required by scrypt_jane.so" btw, google says it's a bit complicated.  

Edit: Just after i wrote this the pool crashed with massive ammounts of these errors. Getting the same errors in the old version too, i'm actually thinking of a malicious miner delivering shares that crash the pool, if such a thing is possible. Will test both versions a bit, the new one has nice and low DOA indeed, hope i can get it to run stable.

how is your server doing? it seems this method puts more load on the servers. getting alot of "pool not providing work fast enought"

Load average 1.08 1.38 1.35

[eule]

Both new and old versions spazz out on me with massive amounts of these errors after a short time, miners should choose other node until i fixed it.  

edit: Maybe it now works, getting equal amounts of hashes and errors... Wrongly configured GPUs or DDOS, that's the question.

[caish5]

Yeah mine is the same now.
weird, it was fine for hours and now it does it within a minute of startup.

[x3maniac]

same here. ton's of errors. i'm going try to run solo for a few moments to see if this still happens.

eule please keep us posted. i'll also let you know how it goes on my end.. what is your pool address so i can bootstrap you?

[x3maniac]

ok so running this SOLO does not have any errors. not even the gentx error we all been getting. so it's gotta be something between our nodes

[caish5]

I can confirm this.
Maybe one of the nodes was modified badly?

I've gotta sleep I'll leave my one solo overnight and see what happens. It's got 1.5mh's so it should do ok alone!

[x3maniac]

I can confirm this.

can you post your network.py

here is mine

It seems to work ok on my end now, half errors, half hashes.
I thought maybe it's a miner submitting wrong shares, but i don't know if that's possible or how to interpret these errors exactly:

can you check your network.py

i just saw a ealier post caish5 didn't put a block comment to change it to 15 instead of 3

lol i just blocked running solo.  me so lucky!
