I've been mining on p2pool for well over a year without any problems.
Then came the hard upgrade and I've been having problems ever since

I've upgraded to bitcoind to 0.10.2
I've upgraded to p2pool 14.0

BUT . . .

my local p2pool status says:

P2Pool: 11391 shares in chain (2750 verified/11391 total) Peers: 7 (1 incoming)
 Local: 4285GH/s in last 10.0 minutes Local dead on arrival: ~0.0% (0-1%) Expected time to share: 50.9 minutes
 Shares: 18 (0 orphan, 0 dead) Stale rate: ~0.0% (0-18%) Efficiency: ~112.5% (92-113%) Current payout: (0.0365)=0.0365 BTC
 Pool: 689TH/s Stale rate: 11.1% Expected time to block: 3.6 days


but it's WRONG

Coin Cadence says my payout is now zero, and that the Pool rate is 1.5PH/s

*** I deleted the data directory yesterday, either the shares download has failed, or it's taking forever ***
*** the local p2pool global pool rate started higher and has been slowly going down **
*** the local p2pool payout started low and has been going up, while the Coin Cadence payout has been doing the opposite, it started high and worked it's way down to zero! ***

suggestions?
What have I done to break it and how can I fix it?
