Hi,
I got a doveadm panic while running purge -A with 2.2.25
doveadm(x at itronic.at): Panic: file mdbox-map.c: line 1359: unreached
doveadm(x at itronic.at): Error: Raw backtrace:

The command was run in a cleanup script that expunge old mails from the
lazy-plugin.
----
#!/bin/sh
# Permanently expunge old Trash
doveadm expunge -A -d mailbox '#EXPUNGED/*' savedbefore 2w
# Optimize mdbox storage and sis storage
doveadm purge -A
----
After rerunning the command it fails again.
stace could be found after config.
