Mark, FWIW, we are seeing issues with Netscalers as well, on an 8.1 platform. Servers that are part and running get dropped from the LB, etc. We've been working with our system engineers on it, but it may be a limitation in the Netscaler architecture. We asked for F5s....

Had a situation where the second AR Server in the group stopped responding but the load balancing did not detect this and whole server group became inaccessible. Digging a little deeper into the load balancing determined the netscaler pings the per port but doesn’t go any deeper. So in this situation, the port was up and netscaler continued to push traffic to the hung server. Is there something better that netscaler can monitor that would detect when the AR Server stops? If not, is there any way to ensure that if one server quits, everything goes to the other server and users are not interrupted?
