The same device with releng_7 did not show the same behaviour. As these boxes are remote and the watchdog would kick in, I was not able to debug things very much. Even back in the lab, it wasnt always easy to trigger the crash synthetically, but I could. Has anyone done any network performance comparisons between the various branches for speed and stability for single core embedded platforms like the ALIX or Soekris ? ---Mike -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
