I'm still on nwam1-build:2009-08-10.
I have the following configuration that causes nwamd to crash whenever it's
enabled:
bash-3.2# nwamcfg export
create ncp "User"
create ncu phys "e1000g0"
set activation-mode=manual
end
create ncu ip "e1000g0"
set ip-version=ipv6
set ipv6-addrsrc=static
set ipv6-addr="2002:a08:39f0:1:214:4fff:fe20:8224/64"
end
end
create loc "TestLoc1"
set activation-mode=conditional-all
set conditions="ip-address is-in-range 2002:a08:39f0:1:214:4fff:fe20:8224/64"
set nameservices=dns
set nameservices-config-file="/etc/nsswitch.dns"
set dns-nameservice-configsrc=manual
set dns-nameservice-domain="east.sun.com"
set dns-nameservice-servers="127.0.0.1"
end
create loc "TestLoc2"
set activation-mode=conditional-all
set conditions="ip-address is-in-range 2001:db8:1:2::4000/64"
set nameservices=dns
set nameservices-config-file="/etc/nsswitch.dns"
set dns-nameservice-configsrc=manual
set dns-nameservice-domain="nwam.test.com"
set dns-nameservice-servers="127.0.0.1"
end
create enm "TestEnm1"
set activation-mode=conditional-all
set conditions="ip-address is-in-range 2001:db8:1:2::4000/64"
set start="/var/tmp/nwam_tmp/start_TestEnm1"
set stop="/var/tmp/nwam_tmp/stop_TestEnm1"
end
Here's what nwamd is doing at the time:

This is the no-stack corefile I'd mentioned before, but now at least there is
enough information to reliably reproduce and hopefully investigate it.
