Hi, I'm using freebsd-stable.
From almost a year ago, my system crashes when I try to upgrade mysql because
of "sysctl -a" in its configure script.
Immediately after the rebooting, there's no problem but as the uptime
increases,
sysctl always crashes system.
I'm using custom kernel following.
6.2-STABLE FreeBSD 6.2-STABLE #0: Thu Jan 18 08:41:09 KST 2007
Thanks in advance.
Here's the backtrace.
