Question

If you had to programmatically have system create swap files for you, how would you do it?

I am not looking to actually create swap file, but am debugging an issue in own code trying to better understand what did i do wrong that would cause system to create the swap files.

My program (as no doubt you have guessed) is doing a lot of reading and writing of files (extract some data from file A and write it to file B)

What would cause something like this to happen?

UPDATE:

• Please note swap files created are 0 bytes in size.
• Program is written in Java and runs on Linux

Answer 1

As it turns out, the problem came about due to me improperly closing IO connections once files has been read/ written to.

Once i

finally {
    try {
        in.close();
        fstream.close();
        br.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

Swap files stopped being created and issue was resolved.
