Dovecot version: 2.2.25 (7be1766)
I’m looking into an issue we’re having with a new setup. We have one fronted host with two backend hosts, and we’re attempting to use doveadm to allow us to administer sieve on the frontend and have it replicated to the backend hosts.
When I attempt to use doveadm sieve put on the frontend host, i get the following on the frontend host:
frontend-machine $ cat /tmp/default.sieve | doveadm sieve put default
doveadm(root): Error: doveadm server disconnected before handshake: Connection reset by peer
doveadm(root): Error: 10.1.11.82:10993: Command sieve put failed for root: Connection reset by peer
when this happens, on the backend, I see this in /var/log/maillog:
Jan 9 17:00:35 was-imap1 dovecot: doveadm: Panic: epoll_ctl(add, 0) failed: Operation not permitted (fd doesn't support epoll - instead of '<file', try 'cat file|')

Now, if I log in to either of the backend hosts, I can run the sieve put command and it all works out fine, so it’s something in the communication between the frontend and backend.
