So I assume adding connectionTimeout attribute to the connector config could help mitigate this?
André Warnier <a...@ice-sa.com> 24/03/2011 15:15 Please respond to "Tomcat Users List" <users@tomcat.apache.org> To Tomcat Users List <users@tomcat.apache.org> cc Subject Re: Tomcat + apache + mod_jk Hi. The schema is : a) request : browser -(1)-> (apache + mod_jk) --(2)--> tomcat + app. b) response : browser <-(1)-- (apache + mod_jk) <--(2)-- tomcat + app. So let's say that the browser sends the request, over connection (1), to apache. apache creates connection (2) to tomcat, sends the request, and waits for the response. tomcat starts sending the response, which apache reads on connection (2), and starts forwarding it to the browser over connection (1). But, for some reason, connection (1) closes (the user closes the browser or the window, or whatever). Apache would sense that, since it cannot write anymore to connection (1). And it would (probably) close connection (2) then. So tomcat, when it tries to send the next response part back to apache, would find a closed connection (2), and complain. I don't know if the message below is exactly that case, but maybe it explains why other people told you that it could be a network problem. It is not a problem directly of connection (2), but on connection (1), just reflected by apache to connection (2). ar...@bca-group.com wrote: > For the first time we have received this error (many times).
