In my case I believe it is an issue syncing with one of my peers. My recon log shows it discovered 400+ hashes on the peer but then times out trying to download them. I've contacted the peer admin to try to resolve the issue but in the mean time I believe it slows down gossip for me as any keys submitted to that peer have to find their way to me through one of my other peers.
Obviously I need to resolve the peer timeout issue but any advice how I might speed up the gossip process in general? I've noticed looking at the stats that the new/updated keys seem to come in bursts during a window between 1 and 3 am. I suspect that too could be causing my server to drop out of the list until it has a chance to catch up. Timothy A.
