I think your problem is in the line 
$/ = qq{"\$"\t""\t""\n};

I looked at the other thread and what you're using here does not match the data you described there. I have a feeling that your script is trying to find a match for a record separator that doesn't exist, and therefore tried to read the whole file into memory, and got hopelessly bogged down with swapping as a consequence.

Your record separator isn't "$"<TAB>""<TAB>""(newline) is it? I think you need to get rid of all those " characters, for starters...
