Not sure what's the issue with pypy on your machine. Does your CPU show activity when you run it? How much?
pypy cpu usage is lower than 5%, but it seams as anything is verry slow. it look like p2pool on pypy lags. and also get now connection.
but i did now "sudo apt-get update and "upgrade" and gave pypy another changse this day. loocks better for this moment.
But i have to go to work now and look this evening again does pypy work or not. - i will edit this post ....
thanks agein so far jtoomin
