People,
        I sent this out 20 days ago and silence was the stern reply.
Anybody got _absolutely_any_ ideas what could be going on before I
dive head first into the source?


According to Brett Lymn:

Folks,
        I remember a little while ago someone complained about getting
"swap_pager_clean" error messages.  The guy was pretty vague about his
setup so it was hard to work out what was going on.  I too get these
messages like this:

May  4 17:20:36 siren /netbsd: swap_pager_clean: clean of page 536000 failed
May  4 17:20:37 siren /netbsd: swap_pager_clean: clean of page 764000 failed
May  4 17:20:37 siren /netbsd: swap_pager_clean: clean of page 727000 failed
May  4 17:20:37 siren /netbsd: swap_pager_clean: clean of page 6b1000 failed
May  4 17:20:38 siren /netbsd: swap_pager_clean: clean of page 72d000 failed

I don't know if it is significant but my swap is not on my boot device
(boot is wd0 and swap is on sd1b).  I have the correct kernel config
to deal with this.  These messages are a bit of a pain, especially if
I do some heavy X stuff which chews memory. 

I did try reducing the size of my swap by a couple of cylinders but
this seems to make no difference.

Anyone with any ideas at all?

 My config is:

NetBSD 1.0 (no patches)
486DX/25  with 16Meg of RAM
ESDI drive as boot and /usr
SCSI drive as swap and play area

The disk label for the SCSI disk is this:

# /dev/sd1a:
type: SCSI
disk: 
label: 
flags:
bytes/sector: 512
sectors/track: 71
tracks/cylinder: 15

interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0		# milliseconds

3 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:  1990485        0    4.2BSD     1024  8192    16 	# (Cyl.    0 - 1868)
  b:    63900  1990485      swap                    	# (Cyl. 1869 - 1928)
