Påvirkning

  • API-kald til PFMP mislykkes med jævne mellemrum, hvilket potentielt kan påvirke automatiserings- og administrationshandlinger.
  • Gateway-pods reagerer ikke på grund af udmattelse af Java-bunken.
  • Manuel indgriben er nødvendig for at gendanne tjenesten.

 

Cause

This issue is triggered by block-legacy-gateway POST requests and the following API requests: "/api/gatewayLogin", "/api/logout", and "/api/gatewayLogout". The pod handling these requests does not fully release the associated memory upon completion, leading to a memory leak.

 

Resolution

Genstart de berørte block-gateway pods ved hjælp af følgende kommando:

kubectl -n powerflex rollout restart statefulset block-legacy-gateway
