Re: fatal trap 12

Robert & list,

I've catched some more traces (had 4 in the night) and I've changed 
system config to get a crash dump and captured one a few minutes ago. Is 
there anything you need from the crash dump? Unfortunately it's a bit 
too big for an upload (33M over an ISDN connection is a bit to much).

Here are the last 2 traces:

Is there anything else you need for debugging? A cup of coffee? ;)

I'm just wondering why I'm the only one who's got these traps. Nobody 
else cvsup'ed and rebuild recently or did I do something stupid in my 
kernel config (attached)?

Thanks,

Volker
