When the load gets high on Java process i get an error: at java.lang.IllegalStateException: Cannot create a session after the response has been committed at org.apache.catalina.connector.Request.doGetSession(Request.java:2221) at org.apache.catalina.connector.Request.getSession(Request.java:2031) at org.apache.catalina.connector.RequestFacade.getSession(RequestFacade.java:832) at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:216) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:545) at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:494) at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:224) at org.apache.jasper.runtime.PageContextImpl._initialize(PageContextImpl.java:136) at org.apache.jasper.runtime.PageContextImpl.initialize(PageContextImpl.java:113) at org.apache.jasper.runtime.JspFactoryImpl.internalGetPageContext(JspFactoryImpl.java:105) at org.apache.jasper.runtime.JspFactoryImpl.getPageContext(JspFactoryImpl.java:62) at org.apache.jsp.unhandledExceptionIndex_jsp._jspService(unhandledExceptionIndex_jsp.java:51) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:331) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:329) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:265) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.ApplicationDispatcher.invoke(ApplicationDispatcher.java:691) at org.apache.catalina.core.ApplicationDispatcher.doInclude(ApplicationDispatcher.java:594) at org.apache.catalina.core.ApplicationDispatcher.include(ApplicationDispatcher.java:505) at org.apache.struts.chain.commands.servlet.PerformForward.handleAsInclude(PerformForward.java:141) at org.apache.struts.chain.commands.servlet.PerformForward.perform(PerformForward.java:92) at org.apache.struts.chain.commands.AbstractPerformForward.execute(AbstractPerformForward.java:54) at org.apache.struts.chain.commands.ActionCommandBase.execute(ActionCommandBase.java:51) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:190) at org.apache.struts.chain.commands.ExceptionCatcher.postprocess(ExceptionCatcher.java:163) at org.apache.commons.chain.impl.ChainBase.execute(ChainBase.java:209) at org.apache.struts.chain.ComposableRequestProcessor.process(ComposableRequestProcessor.java:283) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1913) at org.apache.struts.action.ActionServlet.doPost(ActionServlet.java:462) at javax.servlet.http.HttpServlet.service(HttpServlet.java:710) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:269) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:188) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:174) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:117) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:108) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:151) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:200) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:283) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:773) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:703) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt(ChannelSocket.java:895) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:689) at java.lang.Thread.run(Unknown Source) I get the error every now and then on a jsp-page and it seems like it occurs when the java-process has high CPU-%. Any clues on what to do? Regards, Alex -- View this message in context:
