Good afternoon, I have a web service that is hosted on tomcat v4. I use the jakarta redirect DLL with IIS to "front-end" the requests. Under load, I receive quite a few exceptions from my client application consuming the web service. The exceptions are all the same and read: "System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."
My workers.properties for the ajp13 connector is setup like this: worker.ajp13.port=8809 worker.ajp13.host=127.0.0.1 worker.ajp13.connection_pool_size=100 worker.ajp13.type=ajp13 worker.ajp13.lbfactor=1 worker.ajp13.cachesize=150 worker.ajp13.cache_timeout=600 worker.ajp13.recycle_timeout=300 worker.ajp13.socket_timeout=30 worker.ajp13.socket_keepalive=1 In my server.xml for tomcat I have: <Connector className="org.apache.coyote.tomcat4.CoyoteConnector" port="8809" minProcessors="10" maxProcessors="150" enableLookups="false" redirectPort="8844" acceptCount="100" debug="0" connectionTimeout="20000" useURIValidationHack="false" address="127.0.0.1" protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/> I am able to put thru ~60 requests per second to give you an idea about load and the client applcation runs 10 threads to generate the load. Out of about 6000 requests I get around 10 to 100 of these failures. If I retry the request, the subsequent request always succeeds so I am a little puzzled. I have done a few things to try and pinpoint the error: 1) Not using IIS and going to tomcat directly over the defined HTTP connector works without error. 2) I receive the same error using the old AJP1.3 connector as I do with the new coyote 1.3 connector. 3) I have tried setting timeouts higher on tomcat or higher on the jk isapi redirect filter with no success. 4) Even debugging all components does not present an additional error. 5) I have been searching Google for the error and some other keywords like "IIS" and "Tomcat" that have resulted in some good results but none that seem to solve my issue. If someone could point me in the right direction I would really appreciate it. This problem is going to drive me to drink! :) What am I missing? Thanks so much in advance for any assistance! - Ian -- View this message in context: http://www.nabble.com/IIS-JK-connector-issues-with-connections-forcibly-closed.-tf4118888.html#a11713813 Sent from the Tomcat - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
