I met a problem: I use the Apache Httpd Web Server as the web-load-balancing. It works as an interface between the Client-User and the back-end program deployed on Jboss. One of the function of the web-application is generating portfolio-report and this is a PDF file. The problem is, if the user click "Generate Report-Light", after a few seconds the user will get the PDF shown in browser. The PDF is small and has just 3 pages. But as the user click "Generate Report" (this report is big and has 300 pages and 7 MB), it takes very long time without end and can not get the PDF shown. I read the mod_jk.log and find the following error messages: [code] [Fri Oct 30 08:22:59 2009] [13902:2537062720] [info] ajp_service::jk_ajp_common.c (2447): (worker_portfolio_son1) sending request to tomcat failed (unrecoverable), because of client write error (attempt=1) [Fri Oct 30 08:23:01 2009] [13902:2537062720] [info] service::jk_lb_worker.c (1384): service failed, worker worker_portfolio_son1 is in local error state [Fri Oct 30 08:23:01 2009] [13902:2537062720] [info] service::jk_lb_worker.c (1403): unrecoverable error 200, request failed.

[/code] If I take out the Http-WebServer, i.g. let the access to Jboss directly, there is no problem. I think it could be the problem of timeout-setting in "workers.properties".
