Re: Dovecot imap-hibernate errors in 2.3.21

Thanks for your reply Aki!

It doesn't seem to contain much more information sadly that points towards anything related to hibernate itself. "Debug: open(/proc/self/io) failed: Permission denied" being the main "thing" that seems a bit odd, but that also happens under 2.3.20 as well by the looks of it:
