From: mru@users.sourceforge.net (=?iso-8859-1?q?M=E5ns_Rullg=E5rd?=) Date: 21 Jul 2002 16:00:09 +0200 Message-ID: User-Agent: Gnus/5.0807 (Gnus v5.8.7) XEmacs/21.1 (Channel Islands) MIME-Version: 1.0 Content-Type: text/plain; charset=iso-8859-1 Content-Transfer-Encoding: 8bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1260 Lines: 29 I noticed that doing lots or file accesses causes the used memory to increase, *after* subtracting buffers/cache. Here is an example: $ free total used free shared buffers cached Mem: 773776 30024 743752 0 1992 10424 -/+ buffers/cache: 17608 756168 Swap: 81904 0 81904 $ du > /dev/null $ free total used free shared buffers cached Mem: 773776 78008 695768 0 26328 10472 -/+ buffers/cache: 41208 732568 Swap: 81904 0 81904 Here 24 MB of memory have been used up. Repeating the du seems to have little effect. This directory has ~3200 subdirs and 13400 files. After a few hours use about 200 MB are used, apperently for nothing. Killing all processed and unmounting file systems doesn't help. Is this a memory leak? I get the same results with ext2, ext3, reiserfs and nfs. -- M?ns Rullg?rd mru@users.sf.net - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
