How to configure bridges to re-connect if the other end restarts? [message #1858570]

I have three brokers: one central and two outliers. The central broker is set to persist messages and has bridge connections with QoS 2 to the two outlying brokers.

However, I am finding that if one of the outliers goes offline for some reason and the bridge breaks, the central broker does not attempt to re-establish the broken bridge.

An example of the bridge connection config:

connection <redacted>
address <redacted>
remote_username <redacted>
remote_password <redacted>
topic # out 2
topic # in 2

Questions:
1 Should the central broker try and re-connect the failed bridge?
2 If so, how do I debug why it isn't?

Bump

This is becoming a serious problem as we are losing connectivity to remote brokers.

I've tried force-setting `keep alive_interval` `restart_timeout` but nothing changes. Sometimes the bridge connects, sometime sit doesn't. restarting the broker may help, but not always. The network connections are over either LANs or VPNs and reliable in every other respect.
