Subject: Possible memory bug in Ruby? I'm stumped!

All-

The code as written after the dashed line way below (with file name t7.rb) correctly inserts the contents of file "intro_subtemplate.txt" into a template file during each iteration, resulting in the creation of some 189 identical but differently named files in directory "./output". (There are 189
filenames in the 189 rows in file "packages.txt".)

However, if I uncomment the two lines starting at "insertb", only 171 files are created, then the program stops with the following message:

  t7.rb:6:in 'initialize': Invalid argument - "./input/intro_subtemplate.txt" (Errno::EINVAL)
       from t7.rb:6:in 'new'
       from t7.rb:6
       from t7.rb:2in 'foreach'
       from t7.rb:2

Interestingly, If I then uncomment the two lines beginning at "insertc", only 128 files are created before the program stops with the a similar message but specifying a different code line from the just-uncommented lines:

  t7.rb:15:in 'initialize': Invalid argument - "./output/SOL_BroadbandManager_6.2_SP1" (Errno::EINVAL)
       from t7.rb:15:in 'new'
       from t7.rb:15
       from t7.rb:2in 'foreach'
       from t7.rb:2

Is this the result of some type of memory leak or improper programming? (Note: I'll ultimatelly have some 6 or 8 files that need to be inserted into each copy of the "main_readme_template" at the position of various tags in this template.) Please help, I'm stumped!

Thanks in advance!!!

File t7.rb:
--------------------------------------------------------------
content = File.new("./input/main_readme_template.txt").read
IO.foreach("./input/packages.txt") { |x|
  field = x.chop.split(':')
  content2 = content

  inserta = File.new("./input/intro_subtemplate.txt").read
  content2.gsub!(/<intro_subtemplate.txt>/, inserta)

  #insertb = File.new("./input/install_unix_subtemplate.txt").read
  #content2.gsub!(/<install_unix_subtemplate.txt>/, insertb)

  #insertc = File.new("./input/files_changed_sp_num-1_subtemplate.txt").read
  #content2.gsub!(/<files_changed_sp_num-1_subtemplate.txt">/, insertc)

  File.new("./output/"+field[0],"w+").write(content2)
  puts field[0]
}
