Last 2 years there is no code changes. Our application is running in only one node.
Our daily data is around 10GB, as our scheduler is removing old data. Our application users also less. Why we got suddenly, these memory leakage problem, when there is no application code change. Problem we are getting only in production environment. We are not getting the same Error in UAT environment, we are using same configuration.
