Also, FYI, I do not have the
http://hg.dovecot.org/dovecot-1.2/rev/0f04c7da33f1 patch installed.

I do have the patch installed to log the fd for this error, but I don't
have the fix http://hg.dovecot.org/dovecot-1.2/rev/401e023c8c29 for
the logging function installed.

Would you prefer that I just let Dovecot run a few days and see if the
problem recurs, or should I install the logging function fix now and
perhaps wait another 7 or 8 days before there may be another failure.

Also, as far as I know, the only dovecot processes running at the time
of the failure were a single master and it's auth and pop3 and imap
login children.
