Does anyone know how to fix the memory issue with cilium? or could link me to the docs or any issues about this. I just followed the instructions to install cilium, most stuff is up, I think tje daemon set is down? more specifically this pod cilium-envoy-chzf8 is in a crashloop of this memory issue, I have 3gbs+ of RAM avalible, but I dont think cilium would take up the rest of my memory nor does it look like size is a issue, here is a example:

               total        used        free      shared  buff/cache   available
Mem:           7.6Gi       4.0Gi       374Mi       197Mi       3.7Gi       3.7Gi
Swap:          511Mi       188Mi       323Mi

The node memory is not the same as the pod memory limits. Do you checkout your pods limits? kubectl describe pod blahblahblah

I increase envoys memory requirement to 1gb, did not fix the issue.
