To: linux-kernel@vger.kernel.org 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 Hello list, While doing massive memory allocation (I'm using GRASS to project NASA's BlueMarble maps) the kernel apparently tries to kill grass but fails. When I try to access /proc//stat the process hangs. For example, an 'strace' of 'ps' ends like this: open("/proc/1783/stat", O_RDONLY) = 6 read(6, I am able to project a few files, but once the filesystem cache fills up, GRASS hangs or gives a panic in vm_stat:381. The strange thing is, very little swap space is in use, and the filesystem cache continues to use most of the RAM. Is this a kernel bug, or do I need to use kernel 2.6.x (I am using kernel 2.4.26) and /proc/sys/vm/overcommit_memory or similar hack? Since I am a kernel-newbie, these links might help explain the problem better ;) http://seclists.org/linux-kernel/2001/Dec/1604.html http://www.mail-archive.com/debian-glibc@lists.debian.org/msg10070.html Brian G __________________________________ Do you Yahoo!?
