Adding more disk space as suggested in issue #115 did not solve the problem (I have 238GB free and 154GB used). The machine has plenty of RAM (15GB, but never uses more than 10) and 8 cores available from the host, and everything was running well for almost a year.\r\n\r\nThanks in advance for your help. I can provide more information if you need.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/opensemanticsearch/open-semantic-search/issues/comments/444450516","html_url":"https://github.com/opensemanticsearch/open-semantic-search/issues/143#issuecomment-444450516","issue_url":"https://api.github.com/repos/opensemanticsearch/open-semantic-search/issues/143","id":444450516,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0NDQ1MDUxNg==","user":{"login":"opensemanticsearch","id":12616389,"node_id":"MDQ6VXNlcjEyNjE2Mzg5","avatar_url":"https://avatars0.githubusercontent.com/u/12616389?v=4","gravatar_id":"","url":"https://api.github.com/users/opensemanticsearch","html_url":"https://github.com/opensemanticsearch","followers_url":"https://api.github.com/users/opensemanticsearch/followers","following_url":"https://api.github.com/users/opensemanticsearch/following{/other_user}","gists_url":"https://api.github.com/users/opensemanticsearch/gists{/gist_id}","starred_url":"https://api.github.com/users/opensemanticsearch/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/opensemanticsearch/subscriptions","organizations_url":"https://api.github.com/users/opensemanticsearch/orgs","repos_url":"https://api.github.com/users/opensemanticsearch/repos","events_url":"https://api.github.com/users/opensemanticsearch/events{/privacy}","received_events_url":"https://api.github.com/users/opensemanticsearch/received_events","type":"User","site_admin":false},"created_at":"2018-12-05T11:16:48Z","updated_at":"2018-12-05T11:16:48Z","author_association":"OWNER","body":"The directory is /var/solr/logs not /var/logs/solr.\r\n\r\nBut it seems its a very old search server package (yet Solr 6), there was an former issue with former single valued author field that if f.e. multiple authors (array instead of string) there was an exception on Solr import, so since some releases f.e. the field author is multivalued and some schema strucutred changed (so after upgrade to Solr 7 schema new indexing of all documents neccessary)."}}
