Hi
I am using mpd5.5 with FreeBSD from 7.2-STABLE
ftp://ftp.freebsd.org/pub/FreeBSD/snapshots/201001/FreeBSD-7.2-STABLE-201001-i386-disc1.iso
to 7.3-RELEASE and 7.3-STABLE, 8.0-STABLE
and every 1-2 day server kernel panic with kernel trap 12
Few people have the same error.
This error in the code was entered presumably in early January 2010.
In 7.2-RELEASE so no this problem.
