ETOOMANYREFS related errors

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?

#uname -a

#dovecot --version

#dpkg -l | grep -E 'dovecot-core|libc6|linux-image'
