Not sure. Many people out there run with epoll without problems.

We've been up and running for 24 hours with "events.mechanism = poll" and no
problems. Let's give it a couple of days to be sure this workaround works. Is
this
issue specific to epoll and the way we have php-fpm configured (to use minimal
resources), or is this is a bug in php-fpm that can ultimately be fixed?

Could you check if it is related to epoll? In your php-fpm.conf file, set:
events.mechanism = poll
to try with "poll" instead. You can also try setting it to "select"
