Are you hitting your pages through an external web server (Apache, IIS) or are you hitting Tomcat (Coyote) directly?
This sounds like a crashed thread. Any indicators in the catalina.out logs? -Jordan ----- Original Message ----- From: "nara" <eval...@gmail.com> To: "users" <users@tomcat.apache.org> Sent: Tuesday, February 28, 2012 4:34:59 AM Subject: Tomcat somtimes responses a blank page.
