Hello All, I have a process, which makes use of recursive function, and in each call, allocates lot of memory on stack. When I run this process on Redhat Linux AS 3.0 (IA-32), (Kernel:2.4.21-4.EL) it has a little strange behavior. Free Memory before running my process: @ 380 MB Free Memory after running my process: @ 80 MB I am sure that my application does not consume this huge memory. (@300 MB) It allocates a very little memory @ 8 KB dynamically, which it frees correctly. My application does not have any memory leaks. I have confirmed it through code-review and rational purify. My doubts are: 1. Is this behavior of kernel is actually a feature (and not a bug) or kernel is unable to recover memory deallocted by a process. (If yes, please let me know if is documented) 2. Are bdflush parameters responsible for this behavior? My current bdflush parameters are as #cat /proc/sys/vm/bdflush 50 500 0 0 500 3000 80 50 0 I tried manipulating these values but no improvement seen. I also tried to process behavior as follows: Instead allocating huge memory on stack, I allocate it dynamically on heap. This way I can ensure the freeing up of memory. But still result is same. One more interesting observation: After running my application once, (kernel has @ 80 MB free memory) I rerun my application but this time there is no drop in free memory. Any input in this regard will really help me. (Thanks anyway for reading this far...) Regards, Kedar. http://www.patni.com World-Wide Partnerships.
