IOException: Too many open files

alle volte ritornano...

qualche utile link per correggere il malfunzionamento:

dove mi ha fatto venire in mente che non facevo:

Finally destroy() your Process.

ma infine utilissimo:

vanno chiusi anche gli stream....

public class ProcDemo {

  public static void main(String[] args) throws

        InterruptedException, IOException {

    Process proc = null;

    try {

      ProcessBuilder pb = new ProcessBuilder(args);

      proc = pb.start();

      proc.waitFor();

    } finally {

      if (proc != null) {

        close(proc.getOutputStream());

        close(proc.getInputStream());

        close(proc.getErrorStream());

        proc.destroy();

      }

    }

  }



  private static void close(Closeable c) {

    if (c != null) {

      try {

        c.close();

      } catch (IOException e) {

        // ignored

      }

    }

  }

}
