I’m sorry. I should have clarified that I took out the specific domain and
path information because I am having this trouble on various sites and it is
not predictable as to when it will happen. But mostly it has been hitting me
as I use various archives on www.ucomics.com, and only because they have
such extensive archives.
Sometimes it will download a few months worth, then crash. Sometimes only a
few weeks would get pulled before crashing. Sometimes I would start it, it
would go a bit, crash… I would restart it from the same place and it would
not crash where it had crashed before.
‘01’.upto(‘12’) do |month|
start = ‘01’
finish = ‘31’
puts “Fetching #{path} from #{domain} starting at #{start} and going to
#{finish} for month #{month}”
h = Net::HTTP.new(domain, 80)
start.upto(finish) do |g|
begin
s = “#{path}#{month}#{g}.gif”
puts “Fetching #{s}…”
resp, data = h.get(s)
puts “Writing #{g}…”
File.open(“doonesbury_2002#{month}#{g}.gif”, “w+”){|b| b.puts data}
rescue
puts “error fetching or writing #{s}, continuing”
end
end
end

No. It’s custom-compiled as part of Gentoo Linux 1.4 (gcc 3.2, GNU
libc2.2.2) compiled with maximum optimization and the Athlon XP switch
turned on. Should I assume this is the problem and recompile with some
different switches?
