Hi,
I'm starting to see, on a pretty standard Debian Jessie installation, some error messages that are apparently related to the ETOOMANYREFS errno.
Firstly, the mail log shows this: dovecot: pop3-login: Error: fd_send(pop3, 18) failed: Too many references: cannot splice
And then the login process fails: dovecot: pop3-login: Internal login failure (pid=34388 id=1) (internal failure, 1 successful auths): user=<username>, method=PLAIN, rip=rip, lip=lip, session=<session>
Is this something that Dovecot should be able to handle, or is it strictly Debian/libc/MySillyMistake related?
