I've got yesterday's -current crash repeatedly (well, three times) under heavy load. We had an array (ccd) of 12 disks and were running 16 random read tests simultaneously. They are all in the same place: === ## gdb -k kernel.4 vmcore.4 GDB is free software and you are welcome to distribute copies of it under certain conditions; type "show copying" to see the conditions.
