Hi, I'm using mod_jk 2.2.27 to connect via AJP to a JBoss backend. The problem is that a reporting application takes a couple of minutes to run a report but mod_jk seems to be closing the connection to the back-end and the user receives a 502 Bad Gateway error. 10 seconds after the request is made, I see the following in the mod_jk logs.:-

I have run a network trace between the web and app servers and it shows there's no AJP traffic at all between them whilst the report is being generated and then the connection being closed after 10 seconds, would socket_timeout close the connection in that case? I don't see any errors about failing cping/cpongs. Kind regards, Phil. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
