Hi, With our production application, I am getting "javax.management.InstanceAlreadyExistsException" error messeges repeatedly before resulting in "OutOfMemoryError". SEVERE: Error registering Catalina:type=RequestProcessor,worker=jk-8009,name=JkRequest9845 javax.management.InstanceAlreadyExistsException: Catalina:type=RequestProcessor,worker=jk-8009,name=JkRequest9845 at com.sun.jmx.mbeanserver.RepositorySupport.addMBean(Unknown Source) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.internal_addObject(Unknown Source) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.registerObject(Unknown Source) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.registerMBean(Unknown Source) at com.sun.jmx.mbeanserver.JmxMBeanServer.registerMBean(Unknown Source) at org.apache.commons.modeler.Registry.registerComponent(Registry.java:871) at org.apache.jk.common.ChannelSocket.registerRequest(ChannelSocket.java:436) at org.apache.jk.common.HandlerRequest.decodeRequest(HandlerRequest.java:443) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:352) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:743) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:675) at org.apache.jk.common.SocketConnection.runIt(ChannelSocket.java:866) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Unknown Source) Jan 21, 2010 5:05:52 PM org.apache.jk.common.ChannelSocket registerRequest WARNING: Error registering request -------------------

When applied the same to JDK 1.5.0_15, I am getting the below errors repeatedly before resulting in "OutOfMemoryError". Since it is production issue, could you please provide a solution for JDK 1.5.0_15 ASAP? Let me know if you need any details.
