You could try force-resync, it is safe to run.

Anyways, without backtrace from core file it's hard to say.

Hello,

Are there any chances that I could fix this issue by running a "doveadm force-rsync" (https://wiki2.dovecot.org/Tools/Doveadm/ForceResync) on this problematic mailbox?

Best regards, Mabi

Hi Aki,

I now ran the following command to force resync all mailboxes:

sudo doveadm -Dv force-resync -u email@domain.com \*

and this gave the following output:

So it looks like it did something but only for the INBOX mailbox. How do I make force-resync do its job on all mailboxes?

After the command I saw that the following file has been modified: "Maildir/dovecot.index.log", that should be the case, right?

Best regards, Mabi

doveadm does not travel over namespace boundaries. you need to run it separately for all namespaces you have with NAMESPACE/* as folder

I see, so with my following namespace config:

namespace inbox { separator = . prefix = INBOX. inbox = yes }

I should use the following command:

sudo doveadm -Dv force-resync -u email@domain.com inbox/*

is this correct? because with this command it does not seem to do anything, even if I escape the '*' with '\*'.

Your separator seems to be . instead of / so maybe inbox.*

Thanks, that was it! Now let's see if I still get this panic...
