    Jboss ESB 4.7 server OutofMemory Error

    john234

      Hi,

       

        we are using Jboss ESB 4.7 server in our test and production environments. when we deploy and run the app server works fine with out any issues. after 3 to 4 days app is throwing out of memory.

      we couldn't run the application even after increasing the memory.  If we delete the Jboss server and install a new server then the same war files are working with out any issues.

       

      what do i need to do to figure out the issue and get the same instance of server working.

       

      Please let me know if you need any more information.

       

      Thank in advance.

          OOM error might have other reasons than heap, you should check that.

          If it is a real memory issue I suppose you have a leak in the server or in your applicaiton.

          You might get a heap dump and analyze which classes are blocking the heap.

            got the Heap dump and analyzed , found the below leak

             

            One instance of "org.hsqldb.Index" loaded by "org.jboss.mx.loading.UnifiedClassLoader3 @ 0x181706a0" occupies 490,928,696 (58.82%) bytes. The memory is accumulated in one instance of "org.hsqldb.MemoryNode" loaded by "org.jboss.mx.loading.UnifiedClassLoader3 @ 0x181706a0".

             

            Keywords

            org.hsqldb.MemoryNode

            org.hsqldb.Index

            org.jboss.mx.loading.UnifiedClassLoader3 @ 0x181706a0

             

            do we have any fix for this.
