The data in swap might be "active" (as in something that's going to be used for some purpose soon), and it might be "inactive" (such as a collection of memory leaks that are not going to be used for anything again). When a process ends, all its allocated memory is freed again - including any use of swap. So no, it is no so that a part of swap space is "taken up" by processes that have ended. | |

Or, to put this question another way, if a process generates some footprint in the swap space, does that part of the swap space NOT get erased (or otherwise marked as available) when that process ends? | |
