Multiple threads: getPort Hangs on 100% CPU with fast infoset on asynchronous invocation ---------------------------------------------------------------------------------------- Key: JBWS-2879 URL: https://jira.jboss.org/jira/browse/JBWS-2879 Project: JBoss Web Services Issue Type: Bug Security Level: Public (Everyone can see) Components: jbossws-native Affects Versions: jbossws-native-3.2.1 Environment: jboss-5.1.0 GA debian 64 bit Reporter: Hajo Krabbenhöft Hi, i'm caching an instance of javax.xml.ws.Service. I cache the results of getPort in a ThreadLocal. When i use multiple parallel asynchronous invocations, this approach does not seem to work, so i invoke getPort for each asynchronous invocation. I have 8 threads using a web service running in parallel on a i7. After about 20h of work, all my worker threads are hanging on: "pool-41-thread-7" prio=10 tid=0x00007f8cc469d400 nid=0x156a runnable [0x000000004691a000..0x0000000046921ba0] java.lang.Thread.State: RUNNABLE at java.util.HashMap.put(HashMap.java:374) at java.util.HashSet.add(HashSet.java:200) at org.jboss.ws.metadata.umdm.FeatureSet.addFeature(FeatureSet.java:63) at org.jboss.ws.metadata.umdm.EndpointMetaData.addFeature(EndpointMetaData.java:375) at org.jboss.ws.core.jaxws.client.ClientFeatureProcessor.processFeature(ClientFeatureProcessor.java:84) at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.initWebserviceFeatures(ServiceDelegateImpl.java:537) at org.jboss.ws.core.jaxws.spi.ServiceDelegateImpl.getPort(ServiceDelegateImpl.java:526) at javax.xml.ws.Service.getPort(Service.java:607) at com.spratpix.subdomains.ThreadLocalWebserviceProxy.getAsyncPort(ThreadLocalWebserviceProxy.java:47) Here is how i use getPort protected T getAsyncPort() { long t0 = System.nanoTime(); try { return service.getPort(portClass, new FastInfosetFeature()); } finally { long dt = System.nanoTime() - t0; TimingInterceptor.callChain.addInvocationWithMethod(method, dt); } } And the problematic web service call seems to be public Future<Boolean> PutFileAsync(String domain, String type, String filename, S3Object file, AsyncHandler<Boolean> asyncHandler); -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
