Ruptime/rup? And Cookie problem when DR

Ok my LB seems to work now but i have some little problems.
I tried ruptime and rup but always i get the error in log:
May 23 08:49:51 lb nanny[2472]: The following exited abnormally:
May 23 08:49:51 lb nanny[2472]: failed to read remote load
May 23 08:50:09 lb nanny[2472]: The following exited abnormally:
May 23 08:50:09 lb nanny[2472]: failed to read remote load
May 23 08:50:27 lb nanny[2472]: The following exited abnormally:
May 23 08:50:27 lb nanny[2472]: failed to read remote load

I made an ssh key i can directly connect form lb to the realhost as root
via ssh
So what is the problem there?

My other problem is, that it seems that when i try to reach my website
wich is loadbalanced i get error messages from the InternetExplorer that
i haven't enable cookies for this sit ebut i did.
When i bound the site to the vhost on the realip of the virtualhost then
it works fine!
