Well, this is embarrassing.
My worker became unreachable after 120s of inactivity, so clearly there
was some network state timeout issue.
I was tweaking everything server side and client side to no avail. Then
it hit me: I had totally forgotten that this particular client was
behind a NAT'ing residential gateway, so of course push messages from
the server won't get through after some point of idling.
rabbitmq-server has a built-in heartbeat, but debci doesn't use it, and
my attempts to activate it led to frequent terminations, for subtle
reasons and/or bugs. In the end, I just used TCP keepalive. All is fine now.
