Hi Erick, In continuation to my below mails, I have a socket based multithreaded server that serves in average 1 request per second. The index size is 31GB and document count is about 22 millions. The index directories are first divided in 4 directories and then each subdivided to 21 directories. I share a ParallelMultiSearcher instance for all the searches without closing the readers. I have given the JVM 5GB of memory.
Normally server runs smooth but sometimes when there is some complex phrase query with other fields executed, it gives below error and hangs. I think that there is no sorting for the query that creates below error, please help. java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space at org.apache.lucene.search.ParallelMultiSearcher$ExecutionHelper.next(ParallelMultiSearcher.java:278) at org.apache.lucene.search.ParallelMultiSearcher.search(ParallelMultiSearcher.java:139) at org.apache.lucene.search.Searcher.search(Searcher.java:53) Caused by: java.util.concurrent.ExecutionException: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space at java.util.concurrent.FutureTask$Sync.innerGet(Unknown Source) at java.util.concurrent.FutureTask.get(Unknown Source) at org.apache.lucene.search.ParallelMultiSearcher$ExecutionHelper.next(ParallelMultiSearcher.java:274) ... 6 more Caused by: java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space at org.apache.lucene.search.ParallelMultiSearcher$ExecutionHelper.next(ParallelMultiSearcher.java:278) at org.apache.lucene.search.ParallelMultiSearcher.search(ParallelMultiSearcher.java:139) at org.apache.lucene.search.MultiSearcher$MultiSearcherCallableWithSort.call(MultiSearcher.java:428) at org.apache.lucene.search.MultiSearcher$MultiSearcherCallableWithSort.call(MultiSearcher.java:402) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) at java.util.concurrent.FutureTask$Sync.innerRun(Unknown Source) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Caused by: java.util.concurrent.ExecutionException: java.lang.OutOfMemoryError: Java heap space at java.util.concurrent.FutureTask$Sync.innerGet(Unknown Source) at java.util.concurrent.FutureTask.get(Unknown Source) at org.apache.lucene.search.ParallelMultiSearcher$ExecutionHelper.next(ParallelMultiSearcher.java:274) ... 11 more Caused by: java.lang.OutOfMemoryError: Java heap space On Fri, Jun 17, 2011 at 9:28 PM, harsh srivastava <harshc...@gmail.com> wrote: > > Hi Erick, > i will gather the info and let u know. > thanks > harsh > > On 6/17/11, Erick Erickson <erickerick...@gmail.com> wrote: > > Please review: > > http://wiki.apache.org/solr/UsingMailingLists > > > > You've given us no information to go on here, what are you > > trying to do when this happens?
