Hi ,
I am experiencing a problem load balancing 4 Citrix-CSG servers on a Cisco CSS11506 running WebNS 7.40.0.04………
We have 3 independent 3rd party clients which are destination natted to three different internal address, which are internally resolved to the VIP address of 10.139.15.20, Source address is unchanged…. These clients are connected for about 8 hours a day.
The CSS is configured to round-robin between the four Citrix-CSG servers, but it appears to happily all work for approximately a month , then it appears that one of our 3rd party clients appears to be stuck to a single server (Citrix-CSG) according to the sho flows command and does not appear to round-robin, However the remaining two 3rd party clients appear to be round –robin as normal…
Do you have any suggestions why this would be happening?
The current config is as follows:
