Ignite in Kubernetes has problems finding servers
I have experienced the same problem using a GridGain Ignite cluster as Hibernate 2nd level cache within an Azure AKS Kubernetes cluster without being able to explain the problem.
The Ignite cluster works as expected for a few days, with applications joining the Ignite cluster even recovering from temporary network latency failures which are expected in the cloud, then unpredictably applications fail to join the Ignite cluster continuously and eventually the applications permanently fail to join the Ignite cluster.
