Hi Timo-san, Tony-san,
Thank you very much for your comments. In the output of a 'lsof', I see
a lot of the following messages.
>dovecot-a 7346 root 10u sock
0,5 181268 can't identify protocol
>dovecot-a 7346 root 11u sock
0,5 277537 can't identify protocol
I found a quite similar issue posted at:
http://www.mail-archive.com/dovecot@dovecot.org/msg07229.html
I would like to make sure if there is no way to avoid this issue
without updating the dovecot package.
Sincerely,

Run "lsof" or something similar to see what open filedescriptors there

Dovecot...Dovecot was just unlucky enough to be requesting to open a
file when the limit was already reached.
The error message for that situation is actually different:
Too many open files in system
vs.
Too many open files
