No question it's the size.

I wrote a little ruby script to fill up the environment and it the env 
gets whacked as the size approaches 32k.  It does seem like there is a 
little wriggle room depending on how big the string that I am adding 
over and over again is, it fails at different sizes.

require 'utilities.rb'

i = 0
s = "X"

100.times { s += "X"}

#puts s

def env_size()
   result = 0
   ENV.each do | key, value |
      result += value.length();
   end
   return result
end

j = 0
whacked = false
while ( ! whacked && j < 100000)

   env_count = ENV.size()
   verbose( ENV.size().to_s() + ":", 5)
   key = j.to_s()
   value = s;

   already_has_key = ENV.has_key?(key)
   ENV[key] = value.dup

   verbose(ENV.size().to_s()+":ENV[" + key + "] = " + value, 11)
   env_count = env_count + 1

   if( env_count != ENV.size())
      if ( already_has_key )
           verbose("Variable already set.", 5)
        else
           verbose("ENV Hash whacked. " + ENV.size().to_s() + ":" + 
env_count.to_s() + " -> " + key, 1)
           whacked = true
      end
   end
   verbose( ENV.size().to_s(), 5)
   verbose( "Nmbr of Env entries = " + ENV.size().to_s(), 1)
   verbose( "Size of Environment = " + env_size().to_s(), 1)

   j += 1
end


Well ok, thanks for the help.  I guess I have to find a work around.
