Hello
Could you plese
1. send the full output of doveconf -n
2. Check the SOLR logs for any errors
3. Describe your dovecot architecture, ie. if you are running a single backend or a more complex configuration.
4. Provide a backtrace of the core dump using the instructions on https://dovecot.org/bugreport.html
