Hi, I noticed that ExecutorService objects are created in the constructors of ClusterMonitor, ApplicationMonitor, GroupMonitor, ParentComponentMonitor classes. These thread pools' size is 100 [1, 2, 3, 4].
Any idea why thread pools are created per monitor object? Is it not possible to share a common thread pool as per the current design? Stratos server thread count goes beyond 1500 when deploying 2 or 3 apps. And it keeps growing proportional to the deployed app count. This is a very high resource usage.
