I'm wondering if you are using Direct Routing like me with your set of loadbalancers. I think the problem come from direct routing because loadbalancer can't see all the trafic. But the only thing I am sure is that the counters are reseted after timeout and my connections are not dropped.
I'm afraid not, all our systems are setup using masquerading NAT. That was going to be my next question if it turned out (as it did) that you're using kosher RPMs. :) I've only ever had LVSes configured with NAT so have no experience and only a vague memory of how DR works from the docs. If no one here can point you in the right direction there's a dedicated LVS list too which might be worth searching the archives of and then questioning if you can't find an answer. http://archive.linuxvirtualserver.org/html/lvs-users/ Will. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
