even Danbi's is on lower diff fork occasionally ... shut it down and let the chain heal itself ...
I am about ready to quit solo mining too, 1/4 blocks mined orphaned ...

Good to see you back here. This looks FUBR. I tried solo and was mining more orphans than DMDs so I quit. donkeypool is getting hosed with orphans too. There are other coins that are as profitable as DMD right now.
Here is the solution: I've resynced a wallet with maxconnections=7, and 4x connect=, therefore it will stay at right chain and I moved my 800 MH/s from danbi's pool.
