sitecore Caused by: org.apache.lucene.store.AlreadyClosedException: this IndexWriter is closed
sitecore o.a.s.h.RequestHandlerBase org.apache.solr.common.SolrException: Exception writing document id
For last few weeks I was getting this exception while I was working on my local machine using a copy of production master and web databases. It never happened before, never with our dev databases synchronized by Unicorn. Rebuild started normally, and then half an hour later I was getting an exception pointing into a random item saying that Sitecore is not able to write document ID. Data corruption? But why is working on staging? No, the Java heap is running out of space.
