[lvs-users] Upgraded my Load Balancers, Performance Went to Sh*t

[Eric Robinson]

That's the odd part. We don't have any WRR health checks at all. Everything is WLC. And the ldirectord.cf file did not change, not did the version of ldirectord itself. I have checked through the file, and there are no virtual servers that are not backed by realservers, and there are no realservers showing in a down state. I would post the file but it is quite long. We have approximately 1700 virtual services configured.

Eric,

What kind of health checks are you using, it sounds like no backend servers available in the cluster?
