Hello,
when doing a simple search through the lucene indexes in some
mailboxes (with actually many subfolders) the search terminates
after a few seconds with no result and the dovecot log shows this
error:
Fatal: master: service(imap): child 15433 killed with signal 6
(core not dumped)
Any clue about the reasons? the lucene indexes have been already
rebuilt and look OK.
Regards
