One of my users just informed me he can force an immediate panic by writing a large file to ~ftp/pub/pcg (which is mounted to ~pcg/ftp_data with mount -t null ~pcg/ftp_data ~ftp/pub/pcg). Is nullfs unstable? In fact, I haven't crashed at all since I unmounted them, and it seems there's always a number of ftp connections when the machine crashes. I'm beginning to think this might be the problem. -matt -- Matthew C.
