java.lang.OutOfMemoryError: Direct buffer memory

[aambati]

We are seeing the following exception in the AKHQ logs regularly. We recycle the service , but the error comes back after few hours. Can you please help us. We are running AKHQ in a K8 pod. Currently CPU/Memory is set to:
containers:

    - resources:
        limits:
          cpu: '1'
          memory: 2Gi
        requests:
          cpu: 50m
          memory: 512Mi

Clearly the log is showing that no more memory is available. 512M seems to be to limitated since it's a java app. Can you raise to 1024M to see if it's work ?

[aambati]

Thanks for your response. max memory pod can request is set to 2Gib. 512M is the initial memory allocated to the pod.

My fault, respond to quickly 😅
What version of akhq are you using ?

[aambati]

0.2.2 (https://artifacthub.io/packages/helm/akhq/akhq/0.2.2)
