[Linux-cluster] Re: Trying to locate the bottleneck

[Raymond Setchfield]

Hi Henry

Unfortunately not, however I did get this output from /var/log/messages

Jul  9 11:45:41 loadbalancer-01 kernel: Netfilter messages via NETLINK 
v0.30.
Jul  9 11:45:41 loadbalancer-01 kernel: ip_conntrack version 2.4 (12289 
buckets, 98312 max) - 228 bytes per conntrack

Thanks

R.
