This happens quite often for me. One peer; sync stalls after a while. Target keeps increasing as expected.

Maybe useful. I wonder if the problem is some ancestor query on import.

Are there any sync logs? Also it looks like there's only one peer connection. Was that peer behaving normally?

Is that 25 seconds?

I think so, sorry I didn't have more traces at that point.

@gavofyork is this still an issue? Trying to determine if there are any red flags to launching Centrifuge's mainnet shortly. Thanks!
