Sarge - Minimum System Requirements
I had the main distribution installed on my P166 with
64mb of RAM running for the longest time. With a crash
of the harddrive; I installed Sarge being that it very
close to going gold. Running the machine for the past
few days I am frequently experiencing out of memory
errors in perl. So I investigated a little bit and see
that the MemFree on the machine is fairly low; I have
seen it get down to 1300kb. Now I have attached output
from ps and top to show that there isn't really much
running on the machine. Why is the kernel taking up so
much memory ? I never had this problem in the past
distributions I ran. Looking a minimal requirements I
don't see how I could possibly get it running on a
16mb machine :-)
I have stopped the apache daemon and I can get it up
to about 9000kb free; but that still leaves about
another 55 mb out there.
Comments, suggestions other than putting more RAM in.
I don't seem to have any more old 72 pin RAM I can put
in the machine.
