I have 8GB memory and also plenty of available ruby memory limit virtual memory. When I am doing this I have more than 5GB RAM available. The largest file in the directory is 3.8 GB. The script is file_count = 1 File.open("allscraped.txt", 'w') do |out1| for file_name in Dir["allParts/*.dat"] do puts "#{file_name}#:#{file_count}" file_count +=1 File.open(file_name, "r") do |file| source = "" tmp_src = "" counter = 0 file.each_line do |line| scraped_content = line.gsub(/<.*?\/?>/, '') tmp_src << scraped_content if (counter % 10000) == 0 tmp_src = tmp_src.gsub( /\s{2,}/, "\n" ) source << tmp_src tmp_src = "" counter = 0 end counter += 1 end source << tmp_src.gsub( /\s{2,}/, "\n" ) out1.write(source) break end end end The full error code is: realscraper.rb:33:in `block (4 levels) in

Bad news—Ruby (MRI) can cause an out-of-memory server crash. The issue has first appeared with version 2.2.0-preview and remained ever since. Good https://evilmartians.com/chronicles/ruby-2_2-oom news—the mysterious bug has finally been dealt with. It https://groups.google.com/d/topic/ruby-fog/0iRNNfrHp8Y was extremely difficult and took me quite a lot of time and effort. This madness of a bug-fixing deserves a separate post, and I promise I’ll describe it in all detail. Now I would like to explain what this bug and my patch are about. failed to To start with, this would have been impossible to achieve without the support of my friends Ravil Bayramgalin, ruby-debug expert who showed me the ropes and was with me from the very beginning, and Vladimir Menshakov, outstanding C-specialist who helped me with the C aspects of Ruby application debug. So, Ruby failed to allocate (MRI) interpreter is written in C. It means that many standard Ruby library methods are implemented in C as well. Ruby MRI uses the YARV virtual machine to interpret the code. Hence, a Ruby program has two stacks—a Ruby one and a C one. In the main thread of your program, the C stack is limited to the standard stack value used in *nix systems (sysctl kern.stack_depth_max) which is 8 MB by default, while the Ruby stack is limited to the vm_core.h value which is 1 MB by default. You can change it by setting the environment variable. export RUBY_THREAD_VM_STACK_SIZE=10000000—this is the command I used to set the Ruby stack limit to 10 MB for all the programs. It is very easy to write a recursion or create a self-referencing object with Ruby. For instance, it could be done like that: def recursion recursion end recursion # => StackOverflowException # example 2 class van GoogleInloggenVerborgen veldenZoeken naar groepen of berichten
