Wolf0, reboot pool
plz
I'll restart it, but not certain that will help.
if you use on pool my old p2p scrypt, try to do this:
1) check connected nodes on your ani daemon.

3) backup and clean folder data in p2pool folder(p2pool/data/animecoin/... --> p2pool/data/ empty)
4) start p2pool
On my old pool i use this procedure every few days.
NB: when you clean folder data, all p2pool mine statistics will be lost. And next few days pool work normal.
