Version?

FYI the odds of a successful connection are about 1 in 5. This is why version3 uses batch connection when generating connections from the pool.

It is however possible that the pool can become starved of good connections, as the connections are supplied by peers (not just at startup) and there is no DoS protection. I have found that actual problems here are rare and given other more significant necessary work I haven't prioritized making the host pool more robust. The first step is to actually manage the pool, aging connections out, requesting more when needed, falling back to seed nodes at some point. I wouldn't restart to do this as it's very disruptive and there's really no reason to do so.

This is wrong. Of course it was created when I stopped the node.

However the node getting stuck cycling through hosts that don't work makes initial sync difficult.

Maybe there can be a piece of code whereby if there isn't a connection after X attempts, then it will restart the bootstrap process and clear the hosts cache. How does that sound?
