System.OutOfMemoryException .net core docker in k8s

Hello ,
Not sure how to go about troubleshooting this issue and thought maybe someone could point me in the right direction. I’m running a .net 5 ( tried with 3.1 as well) on k8s with a docker running the 5.0-buster-slim. When performing continuous request operations on large datasets I get a System.OutOfMemoryException. The node I have has 4gb ram with 2.5 usable. The deployment allows for 2gb ram for my pod. I tried setting “System.GC.Server”: false to work in a workstation GC mode. as well as setting the System.GC.HeapHardLimit
Appreciate any reply.
Thank you.

Hello,
the solution simple is to add more resources to your pods: CPU and memory the elaborate solution: refactor your code to reduce async and await calls
the GC is a headache …
you can get more details running your app with this large dataset running in localhost with Docker/docker-compose and controlled resources, maybe monitoring container resources with DockStation …
currently, we handle the extraction, transformation, and loading of more than 1M rows per request smoothly with 8G ram and 2 vCPU assigned to the pod, ending with more than 60M of rows in the Postgresql database server in 20 minutes …
my recommendation: assign more resources to your pods …
best regards ;)
