I believe I found my gremlin... sitting here this morning, and asterisk restarted. hmmm... I happened to be logged into the node box via ssh (backyard repeater -is- at the house, just in a different room, with no monitor) and got the 'Segmentation fault' error messages scrawled across the screen... time to fsck that drive! (did that for you, Duuuuuuuude) ;-)
