In my log I have a lot of log entries like this one (covering one hour of logs here):

May 15 09:00:49 dict: Info: maildatabase: Disconnected from database, retrying commit May 15 09:17:10 dict: Info: maildatabase: Disconnected from database, retrying commit May 15 09:22:30 dict: Info: maildatabase: Disconnected from database, retrying commit May 15 09:31:07 dict: Info: maildatabase: Disconnected from database, retrying commit May 15 09:37:15 dict: Info: maildatabase: Disconnected from database, retrying commit May 15 09:39:36 dict: Info: maildatabase: Disconnected from database, retrying commit May 15 09:50:49 dict: Info: maildatabase: Disconnected from database, retrying commit

7 times per hour, that's quite a bit. Dovecot 2.1.17

Related logs look like:

May 15 00:16:44 imap(username): Info: save: box=Sent, uid=1196, msgid=<5373EB4A.90306@sys4.de>, size=11152 May 15 00:16:44 dict: Info: maildatabase: Disconnected from database, retrying commit

or:

May 14 16:10:34 lmtp(7225, username@domain): Info: NTuhEvF1c1M5HAAAcnFQ7Q: msgid=<20090714161800.121200@gmx.net>: saved mail to INBOX May 14 16:10:34 dict: Info: maildatabase: Disconnected from database, retrying commit May 14 16:10:34 dict: Info: mysql(sql.sys4.de): Connected to database maildatabase

So it's reconnecting, but why is it disconnecting/being disconnected in the first place? Does it matter? should I worry?
