Lars Gjestang created SOLR-12487: ------------------------------------ Summary: Possible corruption in tlog after restart of Solr Key: SOLR-12487 URL: https://issues.apache.org/jira/browse/SOLR-12487 Project: Solr Issue Type: Bug Security Level: Public (Default Security Level. Issues are Public) Components: SolrCloud, update Affects Versions: 6.5.1 Environment: Windows server 2012
12 CPU 96GB RAM -DzkClientTimeout=45000-DzkRun --Xms16g-Xmx16g-Xss256k Reporter: Lars Gjestang After restarting Solr we encountered issues replaying tlogs from one of our six shards. The other shards were up and running after a couple hours of replay (due to total tlog of 20gb which we are going to change from "on request" to maxDocs/maxTime). The log first states warnings about "Unexpected log entry or corrupt log" and then we get the following error message: java.util.concurrent.ExecutionException: org.apache.solr.common.SolrException: Unable to create core [VCloud_shard1_replica1] at java.util.concurrent.FutureTask.report(Unknown Source) at java.util.concurrent.FutureTask.get(Unknown Source) at org.apache.solr.core.CoreContainer.lambda$load$6(CoreContainer.java:581) at com.codahale.metrics.InstrumentedExecutorService$InstrumentedRunnable.run(InstrumentedExecutorService.java:176) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at org.apache.solr.common.util.ExecutorUtil$MDCAwareThreadPoolExecutor.lambda$execute$0(ExecutorUtil.java:229) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: org.apache.solr.common.SolrException: Unable to create core [VCloud_shard1_replica1] at org.apache.solr.core.CoreContainer.create(CoreContainer.java:933) at org.apache.solr.core.CoreContainer.lambda$load$5(CoreContainer.java:553) at com.codahale.metrics.InstrumentedExecutorService$InstrumentedCallable.call(InstrumentedExecutorService.java:197) ... 5 more Caused by: org.apache.solr.common.SolrException: Error Instantiating Update Handler, solr.DirectUpdateHandler2 failed to instantiate org.apache.solr.update.UpdateHandler at org.apache.solr.core.SolrCore.<init>(SolrCore.java:965) at org.apache.solr.core.SolrCore.<init>(SolrCore.java:831) at org.apache.solr.core.CoreContainer.create(CoreContainer.java:918) ... 7 more Caused by: org.apache.solr.common.SolrException: Error Instantiating Update Handler, solr.DirectUpdateHandler2 failed to instantiate org.apache.solr.update.UpdateHandler at org.apache.solr.core.SolrCore.createInstance(SolrCore.java:775) at org.apache.solr.core.SolrCore.createUpdateHandler(SolrCore.java:823) at org.apache.solr.core.SolrCore.initUpdateHandler(SolrCore.java:1071) at org.apache.solr.core.SolrCore.<init>(SolrCore.java:936) ... 9 more Caused by: java.lang.reflect.InvocationTargetException at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) at org.apache.solr.core.SolrCore.createInstance(SolrCore.java:761) ... 12 more Caused by: java.lang.StackOverflowError at org.apache.solr.common.util.JavaBinCodec.readVInt(JavaBinCodec.java:998) at org.apache.solr.common.util.JavaBinCodec.readMap(JavaBinCodec.java:612) at org.apache.solr.common.util.JavaBinCodec.readObject(JavaBinCodec.java:298) etc...... ...
