Hi, I am running tomcat 4.1.29, apache 2.0.48, with mod_jk configured on Windows XP. Occasionally, I will receive the following error:
2004-02-23 15:40:07 CoyoteAdapter Requested cookie session id is A02AD09BF242D0D916799B2EBB0FCC92.worker1 2004-02-23 15:40:07 CoyoteAdapter An exception or error occurred in the container during the request processing java.lang.NullPointerException at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:164) at org.apache.catalina.core.StandardPipeline$StandardPipelineValveContext.invokeNext(StandardPipeline.java:643) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:480) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:995) at org.apache.coyote.tomcat4.CoyoteAdapter.service(CoyoteAdapter.java:193) at org.apache.jk.server.JkCoyoteHandler.invoke(JkCoyoteHandler.java:309) at org.apache.jk.common.HandlerRequest.invoke(HandlerRequest.java:387) at org.apache.jk.common.ChannelSocket.invoke(ChannelSocket.java:673) at org.apache.jk.common.ChannelSocket.processConnection(ChannelSocket.java:615) at org.apache.jk.common.SocketConnection.runIt(ChannelSocket.java:786) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:666) at java.lang.Thread.run(Thread.java:534) At which point the web service becomes UNAVAILABLE on port 80 through apache which forwards the requests via mod_jk to the tomcat 4.1.29 servlet engine. I am including some snippets from my server.xml below for the coyote connector. <Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="8019" minProcessors="100" maxProcessors="600" enableLookups="false" redirectPort="8443" acceptCount="10" debug="10" connectionTimeout="60000" useURIValidationHack="false" protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/> I have also configured apache with 600 max threads, see snippet below. # WinNT MPM # ThreadsPerChild: constant number of worker threads in the server process # MaxRequestsPerChild: maximum number of requests a server process serves <IfModule mpm_winnt.c> ThreadsPerChild 600 MaxRequestsPerChild 0 </IfModule> If someone has any idea what I have misconfigured or if you need more information, let me know. I am desperate at this point to find the root of this problem that has been plaguing our website since its release January.
