• Migrating legacy PHP monolith apps on Drupal 8 to Kubernetes

  Alexey Demyanov

  This case study shows how Palark migrated high-traffic Drupal 8 monoliths to Kubernetes to improve resilience, autoscaling, deployment automation, and DDoS handling while reducing infrastructure waste.

• How we found 7 TiB of memory just sitting around

  This blog post tells how the Render team:

  • tracked down Kubernetes memory waste caused by many daemonset namespace watches,
  • fixed config issues,
  • and freed over 7 TiB of memory across clusters by reducing unnecessary listwatch overhead.
• Tracing large job failures to serial console bottlenecks from oom events

  Jack Lindamood

  This case study shows how OOM Killer terminated a critical network daemon on Kubernetes nodes, causing a network outage.

  It covers debugging via serial console and implementing memory reservations to prevent system-critical process termination.

• 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.
