All, We have a simple load balancing arrangement between a Netscaler and two SSL Mid tiers (v18.08).
End users are sporadically encountering session timeout errors when they would not be expected. Sometimes within a few minutes of connecting and in the midst of creating a new incident, they will get a session timeout error (arerr 9201) and they will have to refresh the page and re-authenticate. I've found the following BMC Support KB and shared it with the team: https://bmcsites.force.com/casemgmt/sc_KnowledgeArticle?sfdcid=kA214000000d7ZtCAI Our netscaler resource advises that the cookie-based persistence option is not available when he is configuring load-balancing. I believe he is configuring persistence as IP based. Other than that, we can't identify any non-recommended configuration issues. I suspect that the cookie-based load balancer configuration is significant, but not being a LB expert, it's outside of my skillset and my most convincing argument at the moment is, "...because BMC Support recommends it..." Does anyone have any experience with a basic, simple Netscaler configuration to balance two SSL Mid tiers based on least number of connections (or any other strategy)? Or perhaps session timeouts are a known issue for other reasons that I have yet to stumble across? Thanks, -JDHood
