System is becoming slow after some user space
programs are run and the memory usage displayed
also increasing

is their any known procedure or tools to study
the memory leakage both in user-space and kernel-space

1) Monitor current memory usage taking special care to note current memory statistics
2) Start the suspect program
3) Do stuff
4) Quit the suspect
5) Check back with memory statistics; they should be the same as when you started the program.  If you're missing memory, this is the confirmed leak.

Step 5 isn't as easy as it looks.  The memory leak may only be occurring in a particular part of the program.  For example, if you have a Word Processor, the leak may occur only after executing the Find/Replace functions, not simply from running the program.

Yeah, there are tools out there that make this a lot easier, but I don't know where these tools are on Linux.
