Not sure if we have the same scenario but I got the same error code when I was tryjng to do a lot of requests (updates and queries) with 10 secs of (hard) autocommit to a SOLR instance running in servlet engine (tomcat) with few resources (if I remember no more than 1GB of ram)
Andrea Hi All, I am running a single Solr instance with version 4.4 with Apache Tomcat 7.0.42 ,I am aslo running a Nutch instance with about 20 threads and each thread is committing a document in the Solr index using the Solrj API , the version of Solrj API I use is 4.3.1 , can anyone please let me know if this error is occuring because I am committing documents too fast for a single instance of a server or is it because of any other underlying issue , please let me know. Thanks. org.apache.solr.client.solrj.impl.HttpSolrServer$RemoteSolrException: Server at http://localhost:8081/solr returned non ok status:503, message:Service Unavailable at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:372) ~[DynaOCrawlerUtils.jar:?] at org.apache.solr.client.solrj.impl.HttpSolrServer.request(HttpSolrServer.java:180) ~[DynaOCrawlerUtils.jar:?] at org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:105) ~[solr-solrj-3.4.0.jar:3.4.0 1167142 - mike - 2011-09-09 09:06:50] at org.apache.solr.client.solrj.SolrServer.commit(SolrServer.java:86) ~[solr-solrj-3.4.0.jar:3.4.0 1167142 - mike - 2011-09-09 09:06:50] at org.apache.solr.client.solrj.SolrServer.commit(SolrServer.java:75) ~[solr-solrj-3.4.0.jar:3.4.0 1167142 - mike - 2011-09-09 09:06:50] at com.xyz.DynaOCrawlerUtils.SolrDynaOUtils.createSolrInputDocumentAndPopulateSolrIndex(SolrDynaOUtils.java:101) ~[DynaOCrawlerUtils.jar:?] at com.xyz.DynaOCrawlerUtils.SolrCallbackForNXParser.populateModelToSolrIndex(SolrCallbackForNXParser.java:216) [DynaOCrawlerUtils.jar:?] at com.xyz.DynaOCrawlerUtils.SolrCallbackForNXParser.endDocument(SolrCallbackForNXParser.java:87) [DynaOCrawlerUtils.jar:?] at com.xyz.DynaOCrawlerUtils.SolrDynaOUtils.populateSolrIndexFromCurrentURL(SolrDynaOUtils.java:250) [DynaOCrawlerUtils.jar:?] at org.apache.nutch.fetcher.Fetcher$FetcherThread.run(Fetcher.java:716) [job.jar:?]
