Without much detail about how much memory, swap, etc your system is using, it's anyone's guess really. You say "RAM is not exhausted" but that why would the system be swapping? Maybe you're not looking at it at the right time, it is possible for a process to malloc() large amount of memory and then quickly release it, by the time you look at it, some processes got swapped out, but the memory got released to the system. If you suspect memory leaks, try running "pmap <pid>" on your program and look for which segments are allocated. Dynamic memory would have "anon" next to it and at the bottom you should have the total number of virtual memory in KiB allocated to your process.
