Chain 6 node sync issues

Node can’t seem to keep chain 6 on track (and only chain 6). Receiving conflicting “new tips”, but not recognizing correct as “got new block”. Node has been updated to V1.6. Been running a node for 2 years without any persistent issue. Any help would be appreciated.

Not sure it’s the appropriate fix. But manually blacklisting IP of offending peer connection resolved the issue for now.

You can try the latest master branch - we just push a fix that should address the issue.
