A strange disaster after years of flawless Cyrus work.
After replacing an expiring certificate, I had to reload Cyrus IMAP
3.12.1 on FreeBSD 14.3-RELEASE-p7. Unfortunately, this time Cyrus has
shut down and refuses to start without a clear reason:
*couldn't dup fd 0: Bad file descriptor*
The last lines from maillog:

debug.log no errors at all, the last line is:
Dec 22 18:30:00 … cyrus/master[4127]: ready for work
What “couldn't dup fd 0: Bad file descriptor” mean, where to look for
the snag, how to fix it?
