This session has been closed
Hey, we're seeing this problem (session closed) randomly and in general under heavy load.
25.01.201704:23:19.269 *ERROR* [pool-7-thread-5]com.xxx.global.aem.web.service.widget.WidgetPollingSchedulerRun failed java.lang.IllegalStateException:This session has been closed at com.google.common.base.Preconditions.checkState(Preconditions.java:150) at org.apache.jackrabbit.oak.core.ContentSessionImpl.checkLive(ContentSessionImpl.java:85) at org.apache.jackrabbit.oak.core.MutableRoot.checkLive(MutableRoot.java:172) at org.apache.jackrabbit.oak.core.MutableRoot.getTree(MutableRoot.java:216) at org.apache.jackrabbit.oak.core.MutableRoot.getTree(MutableRoot.java:66) at org.apache.jackrabbit.oak.query.QueryImpl.getTree(QueryImpl.java:1034) at org.apache.jackrabbit.oak.query.ast.SelectorImpl.getTree(SelectorImpl.java:525) at org.apache.jackrabbit.oak.query.ast.SelectorImpl.next(SelectorImpl.java:433) at org.apache.jackrabbit.oak.query.QueryImpl$RowIterator.fetchNext(QueryImpl.java:773) at org.apache.jackrabbit.oak.query.QueryImpl$RowIterator.hasNext(QueryImpl.java:798) at org.apache.jackrabbit.oak.jcr.query.QueryResultImpl$1.fetch(QueryResultImpl.java:108) at org.apache.jackrabbit.oak.jcr.query.QueryResultImpl$1.next(QueryResultImpl.java:127) at org.apache.jackrabbit.oak.jcr.query.QueryResultImpl$1.next(QueryResultImpl.java:91) at org.apache.jackrabbit.oak.jcr.delegate.SessionDelegate$SynchronizedIterator.next(SessionDelegate.java:694) at org.apache.jackrabbit.oak.jcr.query.PrefetchIterator.next(PrefetchIterator.java:97) at org.apache.jackrabbit.commons.iterator.RangeIteratorAdapter.next(RangeIteratorAdapter.java:152) at org.apache.jackrabbit.commons.iterator.RangeIteratorDecorator.next(RangeIteratorDecorator.java:92) at org.apache.jackrabbit.commons.iterator.RowIteratorAdapter.nextRow(RowIteratorAdapter.java:76) at com.day.cq.search.impl.builder.QueryImpl$RowIterAdapter.next(QueryImpl.java:845) at com.day.cq.search.impl.builder.QueryImpl$RowIterAdapter.next(QueryImpl.java:832) at org.apache.jackrabbit.commons.iterator.RangeIteratorAdapter.next(RangeIteratorAdapter.java:152) at org.apache.jackrabbit.commons.iterator.RangeIteratorDecorator.next(RangeIteratorDecorator.java:92) at org.apache.jackrabbit.commons.iterator.RowIteratorAdapter.nextRow(RowIteratorAdapter.java:76) at com.day.cq.search.impl.result.SearchResultImpl.<init>(SearchResultImpl.java:126) at com.day.cq.search.impl.builder.QueryImpl.execute(QueryImpl.java:587) at com.day.cq.search.impl.builder.QueryImpl.getResult(QueryImpl.java:106) at com.xxx.global.aem.web.service.widget.WidgetResourceUtilImpl.getWidgetEndpoints(WidgetResourceUtilImpl.java:50) at com.xxx.global.aem.web.service.widget.WidgetPollingScheduler.poll(WidgetPollingScheduler.java:77) at com.xxx.global.aem.web.service.widget.WidgetPollingScheduler.run(WidgetPollingScheduler.java:60) at org.apache.sling.commons.scheduler.impl.QuartzJobExecutor.execute(QuartzJobExecutor.java:115) at org.quartz.core.JobRunShell.run(JobRunShell.java:202) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745)
The code:
public Set<String> getWidgetEndpoints() throws LoginException, RepositoryException { PredicateGroup predicateGroup = PredicateGroup.create(getQueryParameters()); ResourceResolver resolver = getServiceResourceResolver(); QueryBuilder queryBuilder = resolver.adaptTo(QueryBuilder.class); Query query = queryBuilder.createQuery(predicateGroup, resolver.adaptTo(Session.class)); return getUniqueEndpoints(query.getResult()); } public ResourceResolver getServiceResourceResolver() throws LoginException { Map<String, Object> serviceParams = new HashMap<>(); serviceParams.put(ResourceResolverFactory.SUBSERVICE, SUBSERVICE_NAME); return resourceResolverFactory.getServiceResourceResolver(serviceParams); }
and http://tech.ethomasjoseph.com/2015/09/sling-who-is-closing-my-jcr-session.html and afaik we're not in either of those cases.
Any idea what could be happening?
Thx
