Description:
When autoReconnect is set to true, the driver uses an increasing delay between connection attempts. The time starts out at initialTimeout and doubles for every failed connect attempt. However, this causes the delay time to quickly grow very large (2s, 4s, 8s, 16s, 32s, 64s, 128s, 256s, 512s...), possibly uncessarily extending the downtime.

How to repeat:

Suggested fix:
Two possible solutions to improve the behavior:

-- provide a "cap" setting on the timeout (i.e. 30s)
-- provide a mode which doesn't increase the timeout at all, or at least not exponentially

We've removed the increase of timeouts completely for 3.1.12 and 5.0.0. Thanks for the bug report.
