Following exception is found in solr logs. We are using Solr 3.2. As the stack trace is not referring to any application classes, I couldn't figure out the piece of code that throws this exception. Is there any way to debug this issue?
Is it related to the issue ConcurrentModificationException from BinaryResponseWriter Nov 25, 2013 7:10:56 AM org.apache.solr.common.SolrException log SEVERE: java.util.ConcurrentModificationException at java.util.LinkedHashMap$LinkedHashIterator.nextEntry(LinkedHashMap.java:373) at java.util.LinkedHashMap$EntryIterator.next(LinkedHashMap.java:392) at java.util.LinkedHashMap$EntryIterator.next(LinkedHashMap.java:391) at org.apache.solr.response.XMLWriter.writeMap(XMLWriter.java:644) at org.apache.solr.response.XMLWriter.writeVal(XMLWriter.java:591) at org.apache.solr.response.XMLWriter.writeResponse(XMLWriter.java:131) at org.apache.solr.response.XMLResponseWriter.write(XMLResponseWriter.java:35) at org.apache.solr.servlet.SolrDispatchFilter.writeResponse(SolrDispatchFilter.java:343) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:265) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:541) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) at org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:662) Thanks
