Hello list,
I hope you can help me!
My self-compiled dovecot 2.2.6 (and the two minor versions before, too)
throws that errors:
Nov 28 18:29:00 mailserv dovecot: imap(mar...@example.com): Error:
Transaction log /srv/vmail/example.com/martin/Maildir/dovecot.index.log:
duplicate transaction log sequence (25)
Nov 28 18:29:00 mailserv dovecot: imap(mar...@example.com): Error:
/srv/vmail/example.com/martin/Maildir/dovecot.index log position went
backwards (24,40 < 25,10028)
... and so on ... duplicate transaction log sequences and backwards gone
log positions, and this always, when I use at least two IMAP clients at
the same time (better: the two clients are online and logged in at the
same time).
That happens only with one user (me ;-) ), the other about 15 users on
this server are having no problems.
What I see: the clients are bothering each other, but I don't know, why.
I thought about the used reiserfs filesystem on the server, but there
were no problems with 1.2 on the same server.
Some words about my client setup: I use Thunderbird and iPhone at the
same time, and as a third client on the same Server there is a
Thunderbird instance at my company, which runs parallel to the other
two. Seems to be weired, but isn't really (IMHO ;-) ).
Sometimes there are two TBs at the same mailbox, sometimes only the
iPhone and a TB, sometimes all three.
This runs quite good for long time with dovecot 1.2 and 2.1.x (the last
one at my company in a similary setup with more users and several
clients at the same time).
Maybe there is an error by using "my" build configurations (I think, not)?
---- configures -------------------
./configure \
--prefix=/usr/local \
--with-sql \
--with-ssl \
--with-mysql
-----------------------------------
Here are my dovecot.conf (only the changes of defaults) - maybe there is
a misconfiguration?
