Memory Leaks

I am looking for a tool which can be used to track memory leaks in a
RoR app, i have my site running with Apache2, 20 instances of mongrel
clusters on a windows 2003 server. I came across few tools like
bleak_house and God but they are linux OS based. Has any one tried
such tools in windows.

As per the article in http://mongrel.rubyforge.org/wiki/FAQ, we can
track memory usage by running mongrel using
mongrel_rails start -B

But this command just dumps a lot of data in the log file , I am not
able to interpret it

the dump is something like this

run,classname,last,count,delta,lenmean,lensd,lenmax
1,Float,106655,117957,11302,
1,String,59251,64611,5360,24.858182,136.757360,15791.000000
1,Array,7851,7092,-759,5.576283,25.001869,934.000000
1,Proc,548,1722,1174,
1,Bignum,5054,1623,-3431,
1,Hash,947,1470,523,10.513605,51.913194,692.000000
1,Regexp,1341,1311,-30,
1,Class,1161,1192,31,
1,Rational,2761,1026,-1735,

can anyone explain what conclusion can be drawn from this dump?
