Hi,

We are using clusterip in order to manage load sharing on a small cluster.
This cluster accepts messages from about 3000 sources. 

As it is coded in ./net/ipv4/netfilter/ipt_CLUSTERIP.c, the target procedure
prints messages such as:

hash=1 ct_hash=1 not responsible
hash=2 ct_hash=2 responsible

On a normal day, for a node of the cluster, /var/log/messages contains 691149
of these lines out of 691197 messages.
This is clearly flooding, but I don't want to filter out kernel debug messages.

Could we envisage to get as soon as possible a CLUSTERIP module which doesn't
print such lines by default ?

Thanks
Jc
