Many thanks. I will go and find the related issue. In the mean time, if I cannot control this behaviour it leaves me with problem that I'm finding tricky to solve. Perhaps you can help: My application uses an HASingleton to start certain activities on the master node. It is essential that these activities only occur on one node - hence the HASingleton. However - it is also essential that all web traffic to the application also goes to the master node only - never the slave. Do you know of an http fail-over solution that will ensure that all traffic is directed only to the master node? I.e - not a load balancing solution - pure fail-over.
