The ‘cuirass remote-server’ process goes awry when misbehaved clients
connect; specifically, some of its fibers crash, leaving it running but

I guess what I reported in bug#67633 is a symptom of the above problem,
perhaps?

It could be yes, if ‘remote-server’ crashed right at that moment.

With commit 9a1452ee021c9f773424961cfeef47ca0b7c5c5a, ‘cuirass
remote-server’ handles this situation gracefully.
I’m still curious about who’s sending us garbage: it has to be valid
zmq, just with the wrong number of parts. From the logs, it seemed like
a port scanner or something on the MDC network was sending garbage on
all the open ports, but that would need to be a sophisticated one.
