in reply to Out of Memory 2.

Please, please read How do I post a question effectively?
  1. define 'loaded'.
  2. what OS?
  3. This is perl we are talking about, right?
  4. What have you tried that has not worked?
  5. If you are using Linux, you can use the 'free' command to roughly figure out how much free memory remains

    Good questions. I updated the initial post with the following information:

    1. I have a large equation that I need to manipulate. In a previous post folks tried using a variety of hashes, arrays, strings, etc to handle the manipulation. All attempts ended with Out of Memory. Hence I need to externalize parts of the equation into files or some other non RAM memory store.

    2. Tried on Linux (RedHat), Solaris, Windows XP on 5 machines ranging from 4 core to 8 core with 4-16 gigs of memory.

    3. Yes 5.8 and 5.10

    4. I've tried a variety of PERL based constructs to store and manipulate the symbolic equation - hash, arrays, strings. I've tried a couple different versions of PERL (due to different versions being on different systems)

    5. Thanks! Is there an equivallent for windows?

    Overall I am looking for an approach which I thought would be independent of these tactical factors. That is, if you have a program that runs out of RAM and given PERL is relatively OS independent, is there a common preferred way to manage this situation. I was thinking databases were the way to go but I am not sure.

    I updated the initial post to address these concerns. My thought was that an approach to running out of RAM would be common across all OSs, etc. But perhaps that is not the case?
