I am getting a high amount of orphans since upgrading Litecoin to 8.6.1 and p2pool to 13.4 mining Litecoins.

Shares: 12 total (8 orphaned, 1 dead) Efficiency: 31.46% running ~850kh/s

My other pool installation (not upgraded) running only 300kh/s is currently showing a reward payout amount of ~0.12LTC where my higher upgraded pool is zero.

Is anyone seeing this? or is this just normal variance?
