Error "Data receive failed [Read timed out]" while trying to see the results from an algorithm

Question

Hello all,
I finally got my PA running almost perfectly with HANA online mode.
I tried to execute Apriori at a sample from my data, and then visualize the results. But after more then 2 hours waitting it to open, it gave me this error:
Does anyone knows what it means?
I have already changed the time out for 3000 (it was 300 originally).
I thing it's pretty strange because I filtered to analyse only something about 200 thousand lines!
Can anyone help me with that?
Regards and thanks

There is far too much whitespace in that code.
Anyways, some comments.
void act(BufferedReader src,String line) throws IOException // counting characters
   char[] arrayOfChars = line.toCharArray();
   for ( int i=0; i<(line.toCharArray().length);i++ ) { // length of the line
   ...Why are you calling toCharArray again? You already have a reference to the array.
   for ( int a=0; a<=freqsorted.length; a++){
      temp = new int[(freqsorted.length)+1];
      if(freqsorted[a]<freqsorted[a+1]){
         temp[a]=freqsorted[a];
         freqsorted[a]=freqsorted[a+1];
         freqsorted[a+1]=temp[a];
      System.out.println(freqsorted[a]);
   }Array indices go from 0 to array.length - 1. Your indices go from 0 to length + 1, where are you expecting to get those 2 extra elements from?
