But exactly the same 10.3 worked for you well before? The same configuration, modules, sysctl? Try adding new machines (add new next to another to use different memory/storage space) with the same configuration exactly the same as previously worked fine (10.{2,3}-RELEASE?), so you can track whether this is a hardware or software problem.. mayabe you got into a corrupted memory/storage region or something changed since 10.3-RELEASE that breaks VM compatibility.. Good luck! :-) Tomek -- CeDeROM, SQ7MHZ, http://www.tomek.cedro.info
