Hi,
we are trying to add full text search functionality with Solr to our Doveoct setup. Our Versions:
OS: Debian 9
Tried versions:
- Dovecot 2.2.7 with Solr 3.6
- Dovecot 2.3.4 with Solr 8.2
(2.2.7 from offical Debian repository, 2.3.4 from backports)
Search is working mostly of the time perfrectly smooth. But sometimes following message appears in mail.err:
dovecot: imap(username)<16189><UxYWLVuSYMasEQoK>: Error: fts_solr: received invalid uid '0'
If this error occurs our webmail frontend delivers most of the time a timeout. Sometimes the search only takes really long.
Are there any ideas why this error occurs? We are not able to reproduce the error in such a way that it would always be reproducible. However, we can reproduce the behavior in some form over and over again - but we do not know exactly what is decisive.
If you need any further information please ask - thanks! :-)
