I run the kernel 2.4.20 plus ipvs 1.0.8 too. Just run your commands
"modprobe ip_vs && modprobe ip_vs_wlc" and "ip_vs_wlc && rmmod ip_vs", I
cannot reproduce the same result.
[root@dolphin /root]# modprobe ip_vs && modprobe ip_vs_wlc
[root@dolphin /root]# rmmod ip_vs_wlc && rmmod ip_vs
[root@dolphin /root]# modprobe ip_vs && modprobe ip_vs_wlc
[root@dolphin /root]# rmmod ip_vs_wlc && rmmod ip_vs
BTW, have you seen any kernel Oops in the system logs? Please send me one
(with ksymoops result) if there is.
Maybe you need to do a upgrade your modutils package.
