Hi! We have seen this before but were unable to reproduce the issue.
Could you please send directly to me the core file processed with https://raw.githubusercontent.com/dovecot/core/master/src/util/dovecot-sysreport You should use dovecot-sysreport --core /path/to/core /usr/lib/dovecot/imap as parameters. Also, if possible, index files that match the core from both source & destination server. If you can't provide these, we'll be happy to look just at the core.
