Kernel memory leak

[Bizhan Gholikhamseh \(bgholikh\)]

Hi
I am running kernel 2.6.11 on my platform.
I  think my system has  memory leak either in kernel or application
layer.  
To detect kernel memory leak, I have  been looking at slab information
using slabtop utility. Here are my questions:
1- how to interpret each field? any docs???
2- slaptop shows the "buffer_head" keeps increasing (almost to the
amount that free memory is reducing), what this indicates?
 
 
Many thanks in advance,
Bizhan
