i running Bitcoin Core 14.2
on Windows 10 64Bit
P2Pool V17.0 from http://u.forre.st/u/iqvaqprd/p2pool_win32_17.0.zip
also installed on my computer because all say i need to, Python 2.7.13 32Bit, installed on Phyton is PIP, Twisted, Zope.interface.
i also installed WMI-1.4.9.win32.exe - now idea wath it is

my problem is the Antminer S7 dont connect to my P2Pool node (
http://212.43.81.114:9332). it say in mining status bar my local p2pool server is dead. and work for the second p2pool server (
http://173.212.202.33:9332/static/ - to test). a few times it works for somethink about 1 or 2 minutes ....
this one seams to work
http://77.250.222.254:9332, but there are many p2pool nodes does not work for my. as my one one ... but why ?
Not sure why but I am having the exact same issue ...
It appears to be a issue in the data.py file at line 209 which deals with the segwit and the p2pool is not currently supporting segwit because not everyone has switched to v17 yet.
I believe this is causing issues with the p2pool network and it is knocking the miners off line. I can mine just fine on a different pool.
However if I have the node running even if I am not mining it it will knock my miners off line.
It appears it may also have something to do with the getwork command as this is what appears to trigger the error. If I have the miners off line that error will not appear as the node runs.
However if the miners come online even if they are not mining the node, the node will start throwing that error.
So either there is a flaw in the code for the node or god forbid there could be a DOS issue going on.
