i386
goose was CVSupd, buildworld, buildkernel and installed around 15:00
PDT on 26 MAR, 2008. This was done trying to solve the problem.
The problem showed up from CVSup, buildworld, buildkernel on 14
FEB, 2008 at 11:32 PST.
The other i386 system with same problem and 8 amd64 systems which don't
have the problem were all CVSup'd and built on 14 FEB, 2008 at 11:32
PST.
>Description:
amd(8) is launched on boot (or later) and runs briefly then aborts.
If it is launched on boot then it never gets past reclaiming all
the children it starts to help it boot up. One of the children
(or the parent in some cases) aborts with a SIG 11.
The attached gdb & truss output were obtained by starting amd
manually after boot. It gets past the part where the children
finish setup but eventually dies. Sometimes it is SIG 10, sometimes
SIG 11.
I have a truss output and amd log file available but gnats thought
they were too big to include in the pr email. The core file and
amd binary are available for examination if needed.
The amd.conf and map files are the same on all 10 systems.
>How-To-Repeat:
configure and launch amd on a i386 6.3-STABLE system.
>Fix:
none known.
