[nova-compute] not reconnect to rabbitmq?

Hi,

I'm having a deployment with Ussuri on CentOS 8. I noticed that, in case the connection from nova-compute to rabbitmq is broken, nova-compute doesn't reconnect. I checked nova-conductor who seems keeping trying reconnect to rabbitmq when connection is broken. But nova-compute doesn't seem doing the same. I've seen it a few times, after I fixed rabbitmq and bring it back, nova-conductor gets reconnected, but nova-compute doesn't, I have to manually restart it. Anyone else has the similar experiences? Anything I am missing?

Thanks! Tony
