[JBoss JIRA] Created: (JBREM-1297) Deadlock between MicroRemoteClientInvoker.establishLease and Client.notifyListeners

by Artur Karpinski (JIRA)

Deadlock between MicroRemoteClientInvoker.establishLease and Client.notifyListeners ----------------------------------------------------------------------------------- Key: JBREM-1297 URL: https://issues.jboss.org/browse/JBREM-1297 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.5.4.SP2 Reporter: Artur Karpinski Priority: Critical Deadlock is probably caused by changes introduced in this fix: JBREM-1242. Thread A: 1. MicroRemoteClientInvoker.terminateLease, locks clientLeaseLock 2. Client.notifyListeners, locks connectionValidatorLock Thread B: 1. Client.setupClientLease, locks connectionValidatorLock 2. MicroRemoteClientInvoker.establishLease, locks connectionValidatorLock Please check stacktraces when this deadlock occurred: {code} "Timer-16" - Thread t@486453 java.lang.Thread.State: BLOCKED at org.jboss.remoting.Client.notifyListeners(Client.java:1873) - waiting to lock <747c39d3> (a java.lang.Object) owned by "WorkManager(2)-241" t@6121 at org.jboss.remoting.LeasePinger.stopPing(LeasePinger.java:134) at org.jboss.remoting.MicroRemoteClientInvoker.terminateLease(MicroRemoteClientInvoker.java:434) - locked <751714e> (a java.lang.Object) at org.jboss.remoting.ConnectionValidator$WaitOnConnectionCheckTimerTask.run(ConnectionValidator.java:1081) at java.util.TimerThread.mainLoop(Timer.java:512) at java.util.TimerThread.run(Timer.java:462) {code} and {code} "WorkManager(2)-241" - Thread t@6121 java.lang.Thread.State: BLOCKED at org.jboss.remoting.MicroRemoteClientInvoker.establishLease(MicroRemoteClientInvoker.java:507) - waiting to lock <751714e> (a java.lang.Object) owned by "Timer-16" t@486453 at org.jboss.remoting.Client.setupClientLease(Client.java:2056) - locked <747c39d3> (a java.lang.Object) at org.jboss.remoting.Client.connect(Client.java:1918) at org.jboss.remoting.Client.connect(Client.java:737) {code} One way to fix this would be to add lock on connectionValidatorLock in MicroRemoteClientInvoker.terminateLease. I'm trying to analyse code to check if this fix will not introduce another deadlock problem. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (JBREM-1169) Bisocket connection won't be closed if pulling out the ethernet cable between client and server. The failure detection code won't close the failure connection, as a result, the subsequent requests will hang after connection account exceeds the threshold

by mingjun jiang (JIRA)

Bisocket connection won't be closed if pulling out the ethernet cable between client and server. The failure detection code won't close the failure connection, as a result, the subsequent requests will hang after connection account exceeds the threshold ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBREM-1169 URL: https://jira.jboss.org/jira/browse/JBREM-1169 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Components: detection Affects Versions: 2.2.3.SP1 Environment: OS: Windows Server 2003. JBoss App Server 4.2.3.GA, JBoss Messaging 1.4.5 GA, JBoss Remoting 2.2.3 SP1 Reporter: mingjun jiang We are using JBoss App Server 4.2.3.GA, JBoss Messaging 1.4.5 GA and JBoss Remoting 2.2.3 SP1. In our application, there are a lot of Message listeners running on the client side, these message listeners will receive messages from queue/topic deployed in JBoss Messaging Configuration: We created our own JMS Connection factory which uses the default remoting connector. As you know, the default remoting connector is configured to use the bisocket transport. We didn't change the default value of the remoting connector During we run our application, we open the JBoss web console to monitor the value of currentClientPoolSize under "Jboss.remoting" JMX MBean. How to reproduce this issue: 1. Run 5 message listeners in the client side to receive messages from JBoss Messaging, then we observe the value of currentClientPoolSize is 10 2. After processing several messages, we manually pull out the ethernet cable. The value of currentClientPoolSize is still 10. 3. We run another 5 message listeners in client side, then the value of currentClientPoolSize will become 20 4. After we do the same operations above several times, the value of currentClientPoolSize will increase continuously. Once the value of currentClientPoolSize is equal to the MaxPoolSize, then the subsequent incoming client requests will hang, and we will encounter the following exception in server side 2009-10-20 18:08:09,655 ERROR [org.jboss.remoting.transport.socket.ServerThread] Worker thread initialization failure java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:168) at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) at java.io.BufferedInputStream.read(BufferedInputStream.java:235) at java.io.FilterInputStream.read(FilterInputStream.java:66) at org.jboss.remoting.transport.socket.ServerThread.readVersion(ServerThread.java:859) at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:545) at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:406) at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:173) Conclusion: JBoss Messaging won't close the failure connections if they are caused by manually pulling out ethernet cable. As a result, the value of currentClientPoolSize will increase continuously and finally the new client requests will hang Note: If we killed the process of message listener in client side, then the value of currentClientPoolSize will decrease to 0 immediately, it seems that the server could detect the failure connection and perform the corresponding resource releasing. -- 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

[JBoss JIRA] Created: (JBREM-1054) Annotation to automatically return new transporters types

by David Lloyd (JIRA)

Annotation to automatically return new transporters types --------------------------------------------------------- Key: JBREM-1054 URL: https://jira.jboss.org/jira/browse/JBREM-1054 Project: JBoss Remoting Issue Type: Feature Request Security Level: Public (Everyone can see) Components: r3 api Reporter: David Lloyd Priority: Optional Fix For: 3.1.0.Beta1 It would be cool if a transporter interface (or an implementing class of that interface) could have methods which sport an annotation that indicates that the return value of that method, if it is an interface, should be automatically wrapped into a transporter (if invoked via a transporter). This way, complex remote object structures can be easily created and used. Also handy would be a simple way of notating such methods when the interface and implementation are already existent. -- 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

[JBoss JIRA] Created: (JBREM-1287) getting java.lang.RuntimeException: Unreachable?: Service unavailable. after reaching around 100 odd remote connections

by Dinuka Arseculeratne (JIRA)

getting java.lang.RuntimeException: Unreachable?: Service unavailable. after reaching around 100 odd remote connections ----------------------------------------------------------------------------------------------------------------------- Key: JBREM-1287 URL: https://issues.jboss.org/browse/JBREM-1287 Project: JBoss Remoting Issue Type: Bug Security Level: Public (Everyone can see) Environment: Redhat Linux Reporter: Dinuka Arseculeratne Priority: Critical i am getting java.lang.RuntimeException: Unreachable?: Service unavailable. error within my jbos 4.2.3 app server when doing a load test. During the test when we reach around 100+ remote ejb lookup calls we get this error. It works fine for any connections around 70. After this error comes we have to restart the servers. Our architecture is such that we have the web and app servers separated and remote calls happen between the two servers. -- This message is automatically generated by JIRA.
