i am running vernemq in AWS EKS setup. We build own vernemq image. Below are the setup details
Vernemq version: 2.0.1
No of pods: 2
OS: Amazon linux 2
EKS version: 1.30

Below are, i am faccing issue.

  1. i updated eks cluster to v1.30 from v1.29. After upgrade that vernemq pods going to restart infreaquntly. and also that use more cpu usage

2)when i Rollout restart the vernemq statefulset. its give some error in logs and that affect my application. my application going to crashloop when vernemq restarts. when i restart vernemq pods 1 pod is going to restart and other pod is still in running but that pods logs give some message that is restarted pods is gone in vernemq cluster. after both pods is restarted our application is still crashloop. and i restart our application pods. it is stable after that apllication pods restart.
***main isssue is when vernemq pods restarts application going to crashloop. below is the vernemq pods given logs

i) vernemq-0 pod error:

Permissions ok: Our pod vernemq-0 belongs to StatefulSet vernemq with 2 replicas
Will join an existing Kubernetes cluster with discovery node at vernemq-1.vernemq-headless.vernemq.svc.cluster.local
Did I previously leave the cluster? If so, purging old state.

please review my issue and kindly response.
@ioolkos
@NirmalSenthil NirmalSenthil changed the title vernemq pod restarts after upgrading eks version v1.30 vernemq pods give the error after restart the statefulset. and the application is affected by the temporary unavailability of one VerneMQ pod at a time. Sep 10, 2024
