Category: JBossMQ Group: v3.2 Status: Open Resolution: None Priority: 5 Submitted By: Todd Wolff (wolfftw) Assigned to: Adrian Brock (ejort) Summary: Invalid msgType Concurrency Bug? Initial Comment: Using 3.2.2RC3 Jetty Build, 1.4.2jdk on Windows XP Pro SP1 the attached test case causes an intermittent IllegalArgumentException: Invalid msgType error, when using the UIL2ConnectionFactory. When using the jvm IL (java:/ConnectionFactory), the process simply hangs after a few thousand messages, with no error messages. It may take a few attempts to get it to hang, and the machine should be relatively fast (roughly 100 messages per second) to duplicate the problem. The sessions are all non-transacted, the messages are non_persistent and do not expire. I don't believe I've broken any design idioms within the test case, but if so, please email me with the problem. I've spent several days trying to solve this one. See readme.txt in attached test case for test execution instructions. Thanks and let me know if you need anything else.

I use JVM 1.4.1_01 (Blackdown) on Redhat Linux 8. I was unable to reproduce the problem, even after tens of tries. If all JBoss threads stop running, even unrelated ones then this would suggest a JVM bug, or OS or hardware issue. As 1.4.2 is fairly new, I suggest you test and deploy with a JVM 1.4.1 release. ---------------------------------------------------------------------- Comment By: Adrian Brock (ejort) Date: 2003-08-07 14:29 Message: Logged In: YES user_id=9459 Hi, I've been trying all evening to get either the jvm il or UIL2 il to fail. I've turned off all logging and run different size tests with different numbers of threads. I haven't seen any failures. The UIL2 stacktraces look like the problems we were having with an old version of concurrent.jar (which is used elsewhere by jbossmq), it was replaced with a fixed version for jboss-3.2.0 Can I ask whether you have any old jars in jre/lib/ext or you have modified the classpath to add old jars from somewhere? For Trace2.txt can you go back further in the log so we can see the history for the request that fails: Read msgType: unknown message type 0, msgID: 76057 Regards, Adrian ---------------------------------------------------------------------- Comment By: Todd Wolff (wolfftw) Date: 2003-08-07 13:01 Message: Logged In: YES user_id=839156 Adrian, To get the jvmIL to hang fairly consistently, I had to turn off all logging. It appears to be a race condition. It runs like a champ with debug level logging. ---------------------------------------------------------------------- Comment By: Todd Wolff (wolfftw) Date: 2003-08-07 06:42 Message: Logged In: YES user_id=839156 I get two different errors when using UIL2. Here's the first trace. BTW, it fails everytime unlike the jvm IL. ---------------------------------------------------------------------- Comment By: Todd Wolff (wolfftw) Date: 2003-08-07 06:39 Message: Logged In: YES user_id=839156 Here's the thread dump using the jvm il following the hang. BTW, I'm not using a multiprocessor machine. What I meant by multithreaded was multiple httpclient threads, multiple queue receivers listening on the same queue, multiple queue senders ... I had to run at least six times sending 3000 messages each time to get it to hang. My machine is a Pentium M, 1.3 ghz. It processes the 3000 messages in .489 minutes. I will follow-up with the UIL2 trace. ---------------------------------------------------------------------- Comment By: Adrian Brock (ejort) Date: 2003-08-07 02:19 Message: Logged In: YES user_id=9459 I've tried to get your testcase to crash but it is not happening for me. Probably because I don't have a multi-processor machine. When it hangs using the jvm IL, take a threaddump using ctrl-break and post the results. Alternatively, set TRACE logging for org.jboss.mq while running with UIL2 and post the log snippet for the last couple of minutes before you get the IllegalArgumentException Regards, Adrian ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=784343&group_id=22866 ------------------------------------------------------- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.
