št 19. 9. 2019 o 15:30 Fabian via dovecot mailto:dovecot@dovecot.org> napísal(a): Are there any other hints or tips regarding this „invalid uid ‚0‘"-message? from fts-solr source: case SOLR_XML_CONTENT_STATE_UID: if (uint32_parse(str, len, &ctx->uid) < 0 || ctx->uid == 0) { i_error("fts_solr: received invalid uid '%s'", t_strndup(str, len)); It means that plugin tries to parse '0' when in state of parsing uid in xml response from solr or there is a bug in xml response parser. I would enable rawlog_dir in config and look there for unusual response or extra tags near usual uid in xml response. For example: plugin { fts = solr fts_solr = url=... rawlog_dir=/var/log/fts-solr/ }

Thanks for this tip! The rawlog_dir option is not yet supported in our version 2.3.4. What we could provide now would be the XML-Response from Solr. The corresponding search query sometimes causes this error. But Solr's answer seems to always remain the same - in my opinion this already indicates a bug of Dovecot?

The XML response can be downloaded here: https://owncloud.eideo.de/index.php/s/8oyJaf5HBK6zdbr

Kind regards, Fabian
