Hi,all,
I have install Opensuse 10sp3 (x86_64)+ Open-iscsi 2.865(iscsid) +
Multipath-tools-0.4.7-80, Config and login is ok but I find /var/log/
messages have many conne error, so multipath is change-link many
times, sometime when conn error, the server is hang, such as:

2.6.22.18-0.2, also have, pls help me.Thks.
