[-- Attachment #1 --] Earlier today (while accessing the computer from offsite) I had a crash while executing `mailq`. This system is -STABLE from Saturday night. Since I am rather inexperienced with handling kernel panics I am not sure what all I need to give you. The attachment is the info from gdb. What I find really screwy is that I had run mailq successfully prior to this panic, nor can I see any reason why that seemingly innocuous command could cause a problem. If I need to provide any additional information please let me know what might have happened and how I should go about preventing it (or should I just update my sources again?)
