Eskinews and WWW were rebooted this morning to load some patches in an attempt to resolve the spin_lock hangs. Aton Blanchard provides a patch that fixes one race condition that may be causing our problem, and another that will produce more detailed debugging info and then reboot automatically if it hangs. Both of these were installed this morning. The outage of www2 was caused by operator error, intended to boot www but initially I rebooted the wrong machine. My apologies for that interruption.
