Comment out this line in /usr/local/lib/ipsec/_realsetup:

lsmod 2>&1 | grep "^ipsec" > /dev/null && rmmod ipsec'

I think the next version of openswan will no longer remove any modules upon
stopping, since this is giving is too many problems, and the implicite
switch back to netkey because klips got unloaded.

Check your syslogd.conf then. All messages are logged through syslog
unless explicitely set different in ipsec.conf.

Can you provide us with a gdb backtrace of this? add dumpdir=/tmp to
config setup in ipsec.conf to allow core dumps.
Is this happening with 2.3.0?

do you have this @ip at the other end too? Normaly you specify either the
IP address, a host name, or a literal string. the latter has the "@" prefix.
So "@ipaddress" is rather unusual. But if that is the case for the core,
then I'd love to hear that.

I think you want to configure xauthclient and xauthserver and add the
net group psk in /etc/ipsec.secrets. See README.xauthclient

xauth support, especially to cisco and their proprietary ike extensions is
always interesting :)
