From: Gregory Stark Date: 18 Mar 2003 18:17:07 -0500 Message-ID: <8765qgb6z0.fsf@stark.dyndns.tv> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 4710 Lines: 91 My router box has a problem, it seems to be running out of memory. Programs that worked fine earlier are now swapping like crazy. What confuses me is that if I add up all the RSS of the processes I get 5.9M, a number drastically lower than the available RAM on the machine (24M) and drastically lower than the amount of RAM "free" says is taken (22M). It seems something in kernel space has taken a ton of memory out of play? Or is my diagnosis wrong? USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1 0.0 0.8 1216 196 ?
