I can provide the coredump if needed.

A core dump for this crash would be helpful, since it's not easily reproducible. Please send it to me privately timo.sirainen@open-xchange.com <mailto:timo.sirainen@open-xchange.com> using the tarball generated by dovecot-sysreport --core /path/to/core.

Hi, I sent you the dovecot-sysreport tarball.

Thanks
