    JBoss 3.2.6, communication problems. With -Xdebug, it works OK

    julekmen Newbie



      I have a big JBoss application. Some big C++ (TAO) application  is connecting to it. The C++ app connects to Jboss application at  startup and exchanges some data.
      When I start 1 C++ app, the connection works OK.
      When I start 5 C++ apps simulatenously, none of them can connect and  communicate with JBoss app. Errors start appearing in JBoss log:


      2010-09-16 13:59:37,065 RequestProcessor-6 WARN   [com.siemens.bicnet.servicelocator.BiCNetServiceLocator] No CF Service  Locator registered with the global SL for securityManager
      2010-09-16 13:59:37,829 RequestProcessor-6 WARN  [jacorb.poa] rid: 8  opname: getLicenseKeyList invocation: throwable was thrown, null
      2010-09-16 13:59:37,830 RequestProcessor-6 ERROR [jacorb] org.omg.CORBA.UNKNOWN  vmcid: 0x0  minor code: 0  completed: No

              at org.jacorb.poa.RequestProcessor.process(Unknown Source)
              at org.jacorb.poa.RequestProcessor.run(Unknown Source)


      In case of failure, C++ app tries gets a reference to JBoss app  from NamingService and starts the communication again, but - when there  is one failed connection and there is an error shown above, all  subsequent connection retries fail ( the above error appears in log many  times ) - JBoss app can not recover.


      When I add -Xdebug option to JBoss, and start 5 C++ apps (like  above), in JBoss log I can see one or two errors like these, but next  connection retry succeeds and everything works OK! Surprisingly, JBoss  startup time and connection speed betweed apps is not slower in debug  mode. Can anyone give me a hint, what can be the cause of the problem?..
