Thanks in advance. We have Apache Solr version 6.4.1 installed and configured on Red Hat Enterprise Linux Server release 7.5 and Java is 1.8.0_181. Command to start solr is bin/solr start -c -m 15g
It was working till yesterday. We had to reboot server hardware maintenance activity and post reboot it stopped working. There was no software upgrade done during this activity. I tried to run checkIndex but it failed to execute. On the solr front end I am getting "SolrCore Initialization Failures" coreStore_shard1_replica1: rg.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher Can someone please review and let me know how to recover the system? Below is the error logs which I got from /solr/solr-6.4.1/server/logs/solr.log file. --------- 20YY-MM-DD 11:05:04.327 INFO (main) [ ] o.e.j.s.Server jetty-9.3.14.v20161028 20YY-MM-DD 11:05:04.707 INFO (main) [ ] o.a.s.s.SolrDispatchFilter ___ _ Welcome to Apache Solr™ version 6.4.1 20YY-MM-DD 11:05:04.707 INFO (main) [ ] o.a.s.s.SolrDispatchFilter / __| ___| |_ _ Starting in standalone mode on port 7788 20YY-MM-DD 11:05:04.707 INFO (main) [ ] o.a.s.s.SolrDispatchFilter \__ \/ _ \ | '_| Install dir: /solr/solr-6.4.1 20YY-MM-DD 11:05:04.721 INFO (main) [ ] o.a.s.s.SolrDispatchFilter |___/\___/_|_| Start time: 20YY-MM-DDT11:05:04.708Z 20YY-MM-DD 11:05:04.721 INFO (main) [ ] o.a.s.s.StartupLoggingUtils Property solr.log.muteconsole given.
