    the lmtp service of our dovecot director installation quits with a
    segmentation fault if a lot of mails are simultaneously delivered.
    For example if the postfix mailqueue is filled (for whatever reason)
    and postqueue -f is run the lmtp service quits with a segmentation

    Program terminated with signal 11, Segmentation fault.

    I don't have any ideas why the stream is 0. The configuration of the
    dovecot director installation is attached. Please let me know if i
    shall provide any more information or test something.

    Kind regards
