I had sync problems too. Not with the pool but with other wallet.
Ended up removing everything in the .2017 folder exept for the wallet.dat ofc.
Even after that it still got stuck every few 100 blocks. Killing the 2017d daemon and restarting it several times solved it for now.
I think it has something to do with the fork of earlier this day.
I had lots of this kind of stuff in the debug.log:

getblocks 1290 to 00000000000000000000 limit 500
ThreadRPCServer method=getinfo
getblocks -1 to 00000000000000000000 limit 500
received block 000000000479a83eff6a

I modified the ip in question here, but got lots of misbehaving ips in the log.
