I had the same problem with `doveadm -A` commands after upgrading from Debian
12 to Debian 13 including dovecot upgrade from 2.3.19 to 2.4.1.
My current theory is that changes in how SQL is integrated in 2.4 are causing
the iterate query session to time out during something you do with doveadm and
-A option and a larger amout of users.
I wrote about this last week, you can find it under the title "doveadm backup /
purge problems since migration from 2.3 to 2.4".
My current workarround is a script that generates a user list via doveadm user
'*' , cached this and then execute the doveadm command you need for each user
in this list. Works for me with arround 4k user.
Since this is the second time I heard of that is here anyone else who had the
same problem?
I thought it might be a problem on my end, but it seems to be an issue with
Dovecot 2.4 since I'm clearly not the only one who is affected.
Maybe someone from the dovecot Team has heared about it? Would be nice if this
can be fixed and I can use -A option since before.
