yeah, 6 is the default. restart p2pool and use --p2pool-node 5.9.24.81 and --p2pool-node 198.12.127.2 ... that'll give you 8 outgoing connections, with guaranteed connection to two good nodes
the shares sound perfectly normal for 13gh/s... just a little bit unlucky
(oh, and you got lucky before that.. isn't it like 12hrs per share on avg?)
There is no doubt i had great luck over the weekend.. i had racked up 10 shares with 2 orphans in 3 days. I was using p2pool a few weeks ago and had similar luck, but bitcoind became corrupted and i had to start all over.
Yes, with 13Gh/s, its showing 13hrs per share on avg
