I requested the latest software updates. Which I received links for within the hour. The Loadbalancer.org engineer, Thorsten Wetzig, went beyond just providing the links. He wrote. "I see from the TSD file you sent over to me that you have a slave load balancer as well. I offer you to check the config of your load balancers and then write you a step by step procedure adapted to your configuration. If you like this idea then please send over the TSD from the slave as well." Kind Regards, Thorsten I sent over the slave TSD, he provided an excellent upgrade document adapted to our config.
