[f-nsp] DNS servers behind ServerIRON XL

[Drew Weaver]

                Howdy,

I am curious if anyone has ever ran into an issue where they are using a ServerIRON XL to load balance DNS servers but for some reason one of the DNS servers out of X has an exponentially higher number of connections in show server real <servername> than the other real servers. This behavior is also indicated by the fact that the CPU load on that specific server is at 99% and the others are at 11 or so percent.. I also note that it is ALWAYS the first server in the list which is the exponentially more used server.

At first I thought perhaps people were bypassing the virtual server IP and connecting directly to the real server IP address but then I realized that there is no way that the ServerIronXL would know about the connection under this circumstance (duh..) At any rate does anyone have any thoughts on this phenomenon? It has done this more than once or twice now, and it seems to do it once every 30 days or so. If I restart named on the effected server  it seems to clear it up. I am not running src-nat and the load balancing type is round-robin.

Thanks in advance if anyone has any thoughts ;-)
