As the above Panic is fixed I tried again (see my attached mail to the 
2.3.19 release) and I can confirm to no longer get the Panic, BUT 
authentication is NOT working either :(

Reverting back to a container with Dovecot 2.3.16, get's everything 
working again.

We use a hourly updated local SQLight database and a dict for user- and 
passdb.

Is the usage of multiple backends no longer supported, or did something 
in that regard changed between 2.3.16 and 2.3.19.1?

Here's the relevant part of my config (full doveadm config -n is attached):

userdb {
   args = /etc/dovecot/dovecot-sql.conf
   driver = sql
}
userdb {
   args = /etc/dovecot/dovecot-dict-auth.conf
   driver = dict
}
passdb {
   args = /etc/dovecot/dovecot-dict-master-auth.conf
   driver = dict
   master = yes
}
passdb {
   args = /etc/dovecot/dovecot-dict-auth.conf
   driver = dict
}

The SQLight DB is used for listing all users and to keep the replication running, even if the dict is unavailable.

Any ideas what might be the cause or how to narrow the problem down?

Ralf
