[Valgrind-users] VmRSS, VmData increases with Valgrind

[<Pra...@di...>]

I have written one sample code where I allocate huge memory and then free 
it. What I observed was whenever allocation was done, VmData is increased. 
Whenever that memory is accessed (memset or use it), VmRss is increased. 
When that pointer is freed, both VmData and VmRSS come back to original 
value.

But to test it with valgrind when I check the memory status,  the memory 
is constantly increasing. What my observation is VmRSS is increasing by 4k 
constantly. When it increases by a few times then only VmData is increases 
and eventually VmSize.

Can anybody explain why VmRSS is increasing and VmData is not increasing.

I have verified it on Linux - 2.4 kernel
