Pool building freezes when connections drop during initial setup about r2d2 HOT 4 CLOSED

The pool will retry after failed connection attemps: https://github.com/sfackler/r2d2/blob/master/src/lib.rs#L272-L278.

Lowering the connection timeout will increase the rate at which those retries will be made.

Ah I see, then the freeze might stem from another reason, but it certainly freezes. It normally logs reconnection attempts, but there is no output for like 5 minutes, even though the connection timeout is 30 seconds.
With 5 seconds it somehow errors, maybe the condition is just more difficult to occur.

I don't think I can see how it's possible for initialization to take longer than the connection timeout. A self contained example of your issue would be helpful.

Hmm, I am not able to reproduce it in the setup I expected it to happen. It seems to maybe not be related to the pool start up even, so it might be a diesel or my own issue, so closing this for now! Thank you for the quick response and sorry for any inconvenience.
