Syncing from scratch with those nodes worked for me https://gist.github.com/rfikki/42d7ecd55225fe867855ef2f4cb004d0

possible duplicate of #3288

Does the ancient block import message occur each time the sync fails?

Could use another -l sync=trace log

clearing the entire chain data and resynching appears to help

some news related to this issue / bug?

There are a few long forks on the ropsten network that Parity can't recover from because of the state pruning. We'll be increasing the pruning history size in the next release.
Re-syncing should help for now.

@SinErgy84

@arkpar ok thanks. I'm a little bit concerned, can this happen also on mainnet?

arkpar commented Dec 12, 2016

Large forks on the mainnet are highly unlikely because of the much higher difficulty

Closing as fixed since the pruning history is increased now.
