I had a traffic generator running loading the system to about a 50% cpu load. Sometime in the middle of the night, the box crashed with the initial message AD4 FAILURE - device detached Below are screenshots of the crash debug trace: http://good-times.webshots.com/album/562770794vGgPAL There was heavy network activity and very little disk activity (just the normal system logs I guess). What could be the problem here? Barney ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo! Mobile.
