Doveadm and iterate query

 Hi!

I have a problem with Dovecot on Debian 13:

Dovecot 2.4.1, Debian Trixie

doveadm mailbox path -A INBOX >/dev/null doveadm(email@domain): Error: auth-master: userdb list: User listing returned failure doveadm: Error: cmd mailbox path: Failed to iterate through some users

userdb sql { iterate_query = SELECT email AS user FROM users }

In syslog file: dovecot: auth: Error: auth-worker: Aborted LIST request for *: Shutting down

I have over 30k users in sql DB, doveadm with -A option is dying few second after start with this error, printing about 10% of users. I need much more time (FE command "doveadm expunge -A mailbox Spam savedbefore 3w" could run over 30 minutes).

What I'm doing wrong?
