• Three Weeks in the Trenches: Hunting a 4GB Native Memory Leak That .NET Couldn’t See

  Kalyan Josyula

  This case study shows how a team traced repeated pod OOM kills in ASP.NET Core to native memory growth from zombie SignalR connections, glibc fragmentation, and kernel socket buffers.

• Autoscaling Hid Our LLM Cost Regression (85% → 4% Cache Hit Rate)

  Nick Roan

  This case study shows how a single RAG chunk size change collapsed vLLM prefix-cache hit rate from 85% to 4%, triggering an 80% GPU replica increase while latency stayed flat.

  It also includes the fix: adding a two-phase cache replay gate in CI.

  This case study explains how cURL 65 errors and DNS resolution failures on AWS EKS were caused by Linux kernel network limits being exceeded, resolved by increasing netdev_budget, netdev_budget_usecs, and netdev_max_backlog parameters.

• Orchestrating Secure AI Agents on Amazon EKS

  Matt Camp

  This case study shows how Unitary built Osmia, an open-source orchestration layer on EKS to run autonomous AI coding agents safely at scale using pod isolation, Karpenter, IRSA-based secrets, and real-time trajectory scoring.
