piranha stop balancing

Hi,

My configuration :

One NFS : Linux 2.4.7-10, Red Hat Linux release 7.2

Three Web Servers : Linux 2.4.7-10, Red Hat Linux release 7.2

Two LB (one primary and one secondary) : Linux 2.4.18, Red Hat Linux 
release 7.2

ipvsadm version 1.20

piranha 0.6.1

So, I have three virtual servers (public) with three real servers 
(locals). See lvs.conf at the end of this email. I use direct routing.

I think I have an nfs configuration problem because, when the load is 
approximately at 2 on the nfs, all my httpd process on my web server are 
in state D (waiting for device) and they can't access the data on the 
nfs and the load increase on the web server (10 and more). I have a 
script on the web serveur which stop apache when the load is more than  
10 . So when the script stop apache on the three web server piranah stop 
working and I have to restart piranha on the load balancer.

Sometimes I think piranha stop load balancing only on one virtual server 
???? And again, I have to restart pulse...

Someone can help me to solve these problems ?

Thanks,

Cyrille.
