<p>Hi,</p>
<p>after some tests I notice a difference in dovecot-uidlist line
format when message is read from "old kernel" and "new kernel":</p>

<p>With "old kernel" (where all works fine) UID number are
incremental and in the line there is one more field that start
with "G1611...".</p>
<p>With "new kernel" (where error comes) UID number skip always a
number and the field "G1611..." is missing.</p>

<p>Why Dovecot create different uidlist line format with different
kernel?<br>

I using pop/imap and LMTP via director and user go back in dovecot node
Current: 10.0.100.22 (expires 2021-01-22 17:42:44)
Hashed: 10.0.100.22
Initial config: 10.0.100.22
I have 6 dovecot backands and index via local ssd disk
mail_location = maildir:~/Maildir:INDEX=/var/dovecot_indexes%h
user never log in two different nodes in this same time
I update debian from 8 to 9 (and to 10) and tested via kerlnel 4.x and
5.x and problem exists
If I change kernel to 3.16.x problem not exists
I tested like:
problem exists:
dovecot1-5 with 4.x
and
dovecot1-4 - with 3.19.x
dovecot5 - with 4.x
and
dovecot1-5 - with 5.x
and
dovecot1-4 - with 4.x
dovecot5 - with 5.x
not exists:
dovecot1-5 - with 3.19.x
not exists:
dovecot1-5 - with 3.19.x+kernel-care
I use NetAPP with mount options:
rw,sec=sys,noexec,noatime,tcp,soft,rsize=32768,wsize=32768,intr,nordirplus,nfsvers=3,actimeo=120
I try with nocto and without nocto
big guys from NetApp says "nfs 4.x need auth via kerberos ...."

Hi Maciej,
I'm using LDA for delivery email in mailbox (Maildir) and I
think(hope) that switching to LMTP via director will fix my problem,
but I d'ont know why wiht old kernel works and with recent no.
Are you using POP/IMAP and LMTP via director so any update to dovecot
indexes is done from the same server?

<pre class="moz-quote-pre" wrap="">Hi Maciej,
I had the same issue when I switched dovecot backend from Cento 6 to
Centos 7.
Also my configuration is similar to you, Dovecot Direcot, Dovecot
backend that share Maildir via NFS on NetApp.
For local delivery of emails are you using LDA or LMTP? I'm using LDA.
Let me know.
Thanks

<pre class="moz-quote-pre" wrap="">Hi
I have been trying resolve my problem with dovecot for a few days and I
dont have idea....
My environment is: dovecot director+5 dovecot guest
dovecot-2.2.36.4 from source
Linux 3.16.0-11-amd64
storage via nfs (NetApp)
all works fine but when I update OS from debian 8 (kernel 3.16.x) to
debian 9 (kernel 4.9.x ) sometimes I get random in logs:
Broken dovecot-uidlist
examle:
Error: Broken file
/vmail2/po/pollygraf.xxx_pg_pollygraf/Maildir/dovecot-uidlist line 88:
Invalid data:
(for random users - sometimes 10 error in day per node, some times more)
File looks ok
But if I change kernel to 3.16.x problem with "Broken file
dovecot-uidlist" - not exists
if turn to 4.9 or 5.x - problem exists
I have storage via nfs with opions:
rw,sec=sys,noexec,noatime,tcp,hard,rsize=65536,wsize=65536,intr,nordirplus,nfsvers=3,tcp,actimeo=120
I tested with "nocto" or without "nocto" - nothing changes ......
nfs options in node:
mmap_disable = yes
mail_fsync = always
I bet the configuration is correct and I wonder why the problem occurs
with other kernels
3.x.x - ok
4.x - not ok
I check and user who have problem did not connect to another node in
this time
I dont have idea why problem exists on the kernel 4.x but not in 3.x
