Hi all, I have had a server freeze after about 7 days of uptime. When I got to the terminal the screen was full of this message :- swap_pager: indefinite wait buffer: device: ad0s1f, blkno: 663, size 20480 swap_pager: indefinite wait buffer: device: ad0s1f, blkno: 4096, size 329 The keyboard was frozen but an attempt at another terminal produced something like this :- fatal trap 12: page fault while in kernel mode fault virtual address = 0x2 falt code = supervisor read, page not present IP, FP, S Pointers = various hex panic page fault I ended up rpessing reset. Any offerrs ? Thanks ! I read this on a site and checked the cables / did an entire surface scan with no bad results although elsewhere suggests the disc is on its way out. I dont mind buying another but would like 2nd opinions :) ----------- What does the error ``swap_pager: indefinite wait buffer:'' mean? This means that a process is trying to page memory to disk, and the page attempt has hung trying to access the disk for more than 20 seconds. It might be caused by bad blocks on the disk drive, disk wiring, cables, or any other disk I/O-related hardware. If the drive itself is actually bad, you will also see disk errors in /var/log/messages and in the output of dmesg. Otherwise, check your cables and connections.
