I've a daemon process and I'm allocating heap memory for big character buffers using malloc/free. Each can take 5MB.

Though I freed/deleted memory allocated for the buffers, the increased memory during the allocation time is not re-claiming back.This I observed using top command.

Yes, I think it's glibc - it may keep your memory, with the idea that you'll request it again soon anyway. I don't know if there's a way to force it to give the memory back to Linux.
