:To follow up on my own note, I have since discovered that the swap
:space usage on my disk reported by "top" is slowing increasing for no
:apparent reason.
:
:When I posted the note, the usage was up to 608K. This morning it was
:up to 8xxK, and right now it is 928K. I expect it to be over 1Mb in
:the morning.
:
:This is on a machine with 256Mb RAM and 256Mb swap. It shouldn't ever
:even need to touch swap, and with an Oct 23 kernel, never did. A Dec
:18 kernel (ELF or AOUT) seems to keep growing. The machine isn't doing
:anything different nightly that it wasn't doing before, namely nightly
:"make -j8 buildworld".
:
:Any thoughts on where to start looking in the code for this? At least
:I know the timeframe in which to look (Oct23-Dec18), unless someone can
:narrow it further. Thanks!

I don't think you have to worry about this, it's probably just the
system swapping out totally idle data. You can investigate it a bit
if you want if you are have /proc mounted:
foreach i ( /proc/* )
if ( -f $i/map ) then
cat $i/status | awk '{ print $1 "\t" $2; }'
fgrep swap $i/map
endif
end
