Ever since upgrading the box that our Tomcat server (actually Jboss/Tomcat) resides on from RedHat 8.0 to RedHat Enterprise ES 3.0, we will get very sporadic 500 errors on our JSP pages. When we get one of the errors, if we refresh it right away, the page come back fine.
Mod_jk is set up, to the best of knowledge, correctly, as it worked flawlessly for 12 months in production before we changed our production java box (the apache box stayed the same -- nothing about it changed, not even configuration files).
