Hi, We have an application using tomcat6.0.16 and IIS5 with JK connector.
We found that there are so many errors in the IIS connector log file. [Fri Dec 05 09:13:54 2008] [error] jk_isapi_plugin.c (549): HSE_REQ_SEND_RESPONSE_HEADER failed [Fri Dec 05 09:13:54 2008] [error] jk_isapi_plugin.c (639): WriteClient failed with 00002746 In the tomcat log file, we found the following errors are shown frequently: org.apache.jk.core.MsgContext action WARNING: Error sending end packet java.net.SocketException: Broken pipe ............. WARNING: processCallbacks status 2 I don't known these two errors are related or not and I search the internat and cannot find any solution. My configure in the worker.properties is worker.list=ajp13 worker.ajp13.port=8009 worker.ajp13.host=192.168.15.237 worker.ajp13.type=ajp13 worker.ajp13.socket_keepalive=True My configure in server.xml for 8009 connector is <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" /> Sometimes the users also complaint that the connection is broken when they use our application and click the links too fast. Has anyone can help me? Thanks
