Just for the record, I've had this problem without using vnode backing files. It's exactly the same in all other areas. The machine would lock up at a specific time each week during 'find' in one of the periodic scripts. This occurred when the host and approximately 15 jails executed that command at the same time. Removing the periodic script from the host system solved the problem. This has occurred on a number of machines, and apparently has nothing to do with vn's although that may agravate the problem.
