Description of problem: After upgrading to kernel-smp-2.6.16-1.2107_FC5, Tomcat5 stopped serving applications. A "HEAD / HTTP/1.0" from the command line would return an appropriate header. However, trying to reach the splash page or any apps (e.g. jsp-examples) would hang and/or timeout. Also tried turning off Apache (2.2.0) to make sure it wasn't interfering via ajp13 connector. All apps were working properly prior to using the new kernel, and all apps resumed responding properly when booting the previous kernel (kernel-smp-2.6.16-1.2096_FC5). Perhaps related to bug 190578? Version-Release number of selected component (if applicable): tomcat5-5.5.15-1jpp_6fc (and friends) java-1.5.0-sun-1.5.0.06-1jpp kernel-smp-2.6.16-1.2107_FC5 Reproducible: yes. Actual results: Hang and/or no data returned (empty page). Expected results: Tomcat splash page.
