I have to concur with the following observation. Try to check what the apache processes are doing. If you've enabled server-status on your box and have installed GET (as part of the perl LWP) grep for the pid
GET /server-status | grep <pid-of-proc> or access it http://<server-name>/server-status On older tomcat versions (i.e. 3.2.1), it would seem that older clients (i.e. HTTP/1.0) would hang up on the POST part ie. POST /path/to/form/process.jsp HTTP/1.0 Typically my only recourse is to kill the offending process and/or restart tomcat and apache. kill -9 <pid-of-proc> Hope that helps -Jan-Michael ----- Original Message ----- From: Ben Ricker <[EMAIL PROTECTED]> Date: Thursday, January 2, 2003 9:56 am Subject: RE: is this normal?? > There is probably a problem going on there.
