<br>
i have a problem with index-files which is separated in 2
subproblems. May be these problems are connected.
<br>
Currently we use Ubuntu 18.04 LTS which is bundled with
dovecot 2.2.33.2
<br>
These servers are fresh installed machines and users are added
to the system after, there was no upgrade.
<br>
Sometimes it happens, that dovecot stops showing new mail.
There is no error in log, dovecot just seems to do his normal
operations but is not delivering new emails from
/var/mail/myuser
<br>
emails are delivered again if i delete index-files from .imap
folder. So index is recreated and everything works again. I
cant reproduce this problem, but every 2 days i have one user
who is reporting this problem.
<br>
<br>

<br>
Iam surprised that no one has an opinion in this case. Nobody else
noticed this problem?
<br>
Yesterday i had a customer who was affected twice. First time we
saw an errormessage, which leads to an index problem:
<br>
<br>
Feb 13 15:46:58 hostname dovecot[30097]: imap(username): Error:
Corrupted record in index cache file
/home/popuser/username/mail/.imap/INBOX/dovecot.index.cache: UID
26876: Broken physical size in mailbox INBOX:
read(/var/mail/username) failed: Cached message size smaller than
expected (2118 < 8088, box=INBOX, UID=26876)
<br>
Feb 13 15:46:58 hostname dovecot[30097]: imap(username): Error:
read(/var/mail/username) failed: Cached message size smaller than
expected (2118 < 8088, box=INBOX, UID=26876) (FETCH BODY[] for
mailbox INBOX UID 26876)
<br>
<br>
At this point no new incoming mail is delivered by imapd. We
deleted index files, dovecot reacreated them and all was working
again.
<br>
a day later same user was affected again. But like all other cases
before there is no error or unusual logline. i turned mail_debug
on, but no further hint.
<br>
There are definitely new Mails in /var/mail/username but dovecot
still shows old state from cache. I deleted index-files again and
imap-client showed a lot of new unread mails.
<br>
In log i can see that people are active in imap-clients and
managing mails. If a new mail is coming in this period it seems to
harm index-files some times. We never noticed same behaviour with
long used dovecot 2.2.22
<br>
<br>
It seems that 2.2.33.2 which is bundled with Ubuntu18.04 LTS has a
special problem.
<br>
<br>
Please help. What is your advice?
<br>
<br>
<br>
<blockquote type="cite">
<blockquote type="cite">Second problem is similiar. I Upgraded a
server from Ubuntu 16.04 to Ubuntu 18.04. This includes an
upgrade from dovecot 2.2.22 to 2.2.33.2. After that i
installed an self packaged dovecot 2.2.36.1
<br>
Now here is same problem, dovecot is not showing new mails,
but the difference is we have a Raw backtrace in Log just as
expected:
<br>
<br>
</blockquote>
i think this crash is a special problem of dovecot 2.2.36.1.
<br>
if i downgrade to 2.2.33.2 all is working well, upgrading again
to 2.2.36.1 leeds to same crash.

<div class="moz-signature">A few days ago I posted a similar issue.
My environment has RHEL6 and 7 servers. When I last updated the
servers RHEL6 servers mantained 2.2.10-1_14.el6.x86_64 version,
while RHEL7 updated dovecot from 2.2.10-8.el7.x86_64 to
2.2.36-3.el7.x86_64. When the RHEL7 servers (used for sympa)
processed a message for a user, its indexes were corrupted, and
the user could't access his inbox through webmail, so I had to
delete dovecot.* files from the user mail path to get it working
again. This is the error shown at the dovecot log:</div>
