We have several heavily threaded Java applications running at the time the live-locks occur. At our most problematic site, one application has a bug that can cause hundreds of timer threads (I mean like 800 or so!) to be "accidentally" created. This site is scheduled for an upgrade either tonight or tomorrow, so I will leave the system as it is and see if I can still cause the live-lock to manifest itself after the upgrade.
