We run 3 Policy Servers and our Web Agents are connecting to them, as we defined them in HCO in order: PS1, PS2, PS3, with Failover option set to Yes.
We found that sometimes the Web Agents are not able to failback to recovered Policy Servers.
To illustrate this, suppose we have the following Policy Servers defined following your HCO :
PS1 -- (suppose it is currently down)
When the Web Agent is initialized, it will try to connect first to PS1. As it is currently down, it will fail to connect to it and the Web Agent will attempt to connect to Policy Server PS2, which is available. As expected the initialization will complete correctly. The Web Agent will send requests to the Policy Server PS2. When PS1 is recovered and up again, the Web Agent will not fail back to the Policy Server PS1 and it will continue sending requests to PS2. Why is this behavior and how can I fix this ?
