We have a Dell PowerEdge 2550 server. It's running FreeBSD4-stable
(up'd just a couple of weeks ago). It's an SMP box, 1GB of RAM, two
3com Tigon2 Gigabit NIC cards and a PERC3/QC controller.
We have two logical drives. One is a RAID1 set of two 9GB drives which
holds the operating system only. The other is a 300GB RAID10 array.
The box had been running fine for months when suddenly the box got hosed
as we received tons of these errors on the console. (nothing logged to
/var/log/messages)
swap_pager: indefinite wait buffer: #amrd/0x20001, blkno:272, size:4096
The box only runs as an NFS/Samba server and nothing else. It
eventually just became useless and we had to reset the box hard.
We ran FSCK and it reported no errors and the box came up normally. We
were considering running scanning on the OS disk containing the swap,
but feel there really is no need to as the RAID controller is reporting
no problems as well.
Anyone have any suggestions on where to start looking for this problem?
We've had this unit in service almost six months and this is the first
time we've seen this. Is there a way to "test" swap space in production
other than writing something to gobble up memory and forcing the box to
swap?
