What is really bothering me (currently), is once I start getting connection errors, my CPU usage (roughly) doubles, and I get connection errors much more easily (as if acceptCount was reduced somehow). Any ideas on the cause/solution for this? -----Original Message----- From: Sullivan, Mark E [mailto:Mark.Sullivan@nav-international.com] Sent: Friday, August 09, 2002 10:31 AM To: 'Tomcat Users List' Subject: RE: Configuration for High TPS what version of tomcat are you running?
