Hello,
I just found that with my dovecot 2.2.21, when I use squirrelmail to search for something in my mailfolders, that fails with
ERROR: Connection dropped by IMAP server. Query: SEARCH CHARSET ISO-8859-1 ALL FROM "someone"
That happens for searches in any folder, except from INBOX. When I search in all folders, only results from INBOX are found, then the error message is shown.
The log says:
imap: Error: terminate called after throwing an instance of 'CLuceneError'
imap(christoph): Fatal: master: service(imap): child 2834 killed with signal 6 (core dumps disabled)
What can I do about that?
Lucene library is throwing an error, which crashes Dovecot. Maybe Dovecot should catch the error, but it would still be broken. Try deleting the lucene indexes and rebuilding them?
