When solo mining using P2Pool if you stop mining for an extended time period the share difficulty will become too low and your miners will send shares too fast for P2Pool to handle.
Yes, this happened right after I've stopped miners for maintance for smth about 9 hours.
But, I've tried to use fresh installation of wallet and p2pool on another server and I've got the same result.
How I should fix this problem?
Thanks in advance.
