NimbostratusWe are having least session load balancing setup with SSL persistence.SSL is offloaded at server. It works fine for a while and then all the requests are directed to only one server in a pool of two servers. If we delete and re create the pool, above behavior is repeated again.Any ideas ?

Cirrostratusit should work if everything were configured properly, please share your config.
Employeecan you check persistence table when the issue is happening?

NimbostratusConfig is standard config. When I create the initial pool I can see persistence records for both server IP but later I get persistence records for only one server IP.Also, there are only 3 source IPs that will be hitting the VIP.
