    Application Errors

    David Salter Novice

      I'm not sure if this is the corect forum, because I think I have got a general Java problem, but hopefully someone can help me ;)

      I am getting random General Protection Errors with JBoss running on Windows XP.

      In the event viewer I see that the faulting application is java.exe in module jvm.dll. This is immediately followed by a Fault bucket error. These errors happen seemingly at random when I deploy apps to JBoss, and also when JBoss is sitting idle or executing code - I can't see a pattern.

      Does anyone know what this means or what causes it? Anyone know what a fault bucket is?

      I get the same problem when using

      JBoss 3.2.5, 4.0RC1, 4.0RC2
      Java 1.4.2_03 and 1.5 RC

            I've not got a JBoss log as it was overwritten when I started up again.

            I've got the following Java Log from JDK 1.5 RC if thats any use.

            # An unexpected error has been detected by HotSpot Virtual Machine:

              I have just experienced another crash using JDK 1.5RC

              The end of log file is as follows, there are no errors or anything posted in the log.

              Is there a recommended JVM for JBoss?

                Have a look at the Heap section

                 compacting perm gen total 35072K, used 35025K [0x229a0000, 0x24be0000, 0x269a0000)
                 the space 35072K, 99% used [0x229a0000, 0x24bd4440, 0x24bd4600, 0x24be0000)

                of your VM dump. It says that the permanent generation memory space is full ( 99% used). We too encountered these kind of JVM crash with SUN JVM 1.4.2. Reasons unknown, but try increasing the perm gen memory by adding JVM option


                in <jboss-root>/bin/run.bat and/or run.conf (xx specifies the megabyte count to reserve for perm gen eg. 128).

                Maybe this will solve your problems :-)

                  My latest error log file showed similar info.

                  I'll give this a try.

                  Thanks very much,
