I’ve observed that the memory usage of the Akka Cluster nodes continuously increases, which eventually leads to pod restarts after a certain period. I can clearly see this trend while monitoring the memory usage. I’ve attached a visual representation of this issue below.
To investigate further, I’ve activated Cinnamon on the Akka cluster and started tracking the mailboxes of the system actors. Upon analyzing the data, I identified that mailboxes of actors like ActorGraphInterpreter and TcpOutgoingConnection are growing continuously. I’ve also attached the relevant visuals below.
I am trying to solve the memory issue and would like to know if I am looking at the right place. If this is indeed the right area, how can I prevent the growth of these actor mailboxes? Since these actors are system actors, I cannot intervene directly.
Any insights or suggestions would be greatly appreciated.
