Describe the bug
kube-httpcache container is slowly eating memory. 2Gi memory limit is being eaten within 48 hours.

To Reproduce
Run kube-httpcache.

Expected behavior
Memory usage staying rather stable or at least not increasing steadily over time.

Environment:

  • Kubernetes version: 1.18
  • kube-httpcache version: latest master

Configuration
If that's necessary I can share VCL, but that's pretty much 90% regular Magento 2 VCL.

Thanks for the report! 👍

Just to pin this down: How is the Varnish process itself configured (storage size and storage backend)? Also, is there way for you to determine if the memory consumption is caused by Varnish itself, or by the kube-httpcache controller process?

@martin-helmich Hi! I'm currently trying to pin it down which component is eating the memory. I'll keep you updated.
