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](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?
