IPVS doesn't place any restrictions on the number of rules or connections, although the hardware may have restrictions - for instance you may run out of memory if you have a very large number of concurrent connections. > When the service drops out, the ipvs rules are still in place according > to ipvsadm -L.

Unfortunately I can't shed much light on this problem, other than that I agree that its probably a problem with LVS and not ldirectord (I maintain both, so I'm not buck-passing :-) Do you experience this problem with other kernels? _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
