Bad memory, perhaps? -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
The PAE commits cause some machines to crash like this. It seems to be under load and with low physical memory. ---Mike At 10:49 AM 28/08/2003 -0700, Doug White wrote:>On Thu, 28 Aug 2003, Jonathan wrote: > > > I cvsuped my source at about 0100 GMT 28 Aug and I am still getting > > spontaneous reboots under load.

No crashes happened. I have 160 Mb RAM and 304 Mb swap space. Here is what I did: 1) I started portsdb -Uu (the crashes with STABLE frequently happened when this was running) 2) I ran 5 instances of Octave; having it invert a 2000x2000 random floating point matrix. Five large matrix inversions in all. 3) I loaded the FreeBSD handbook in a web browser to use up more memory. 4) I clicked on the various desktops to make X constantly repaint the screen (I was running Kde at the time). No crashes at all. I could not get FreeBSD to crash. At one point I tried to load a 4000x4000 floating point matrix while all the above was going on but the process was killed. I believe this is the proper behavior; that FreeBSD should kill applications that cause an overload. At any rate the original RELEASE kernel works OK. I also did a memory test and checked out the other components of my laptop with the diagnostic utility. All the hardware checked out OK. I will reinstall as one violent crash damaged some inodes. BTW with the recent STABLE builds never did kill an application that was causing an overload. The notebook just locked up. Kind regards, Jonathan
