Hi Developers, I would like to consult a question about SessionCluster OOMKilled in JobManager
I run a SessionCluster that deploys multiple jobs on K8S, and the JobManager is occasionally OOMKilled by K8S (not JVM Kill), which confuses me very much. The memory size of the K8s request and limit I configured is exactly the same as the value of jobmanager.memory.process.size. I don’t know if this will cause k8s to kill. I set (jobmanager.memory.enable-jvm-direct-memory-limit=true) according to the community guidelines [1], it doesn't seem to improve
Flink Version: 1.16.1
jobmanager.memory.process.size: 1gb
K8S Version: 1.24.x
