Why the Linux OOM Killer Terminates Your Perl Processes on Google Cloud (And How to Prevent It)

Understanding the Linux OOM Killer The Out-Of-Memory (OOM) Killer is a crucial component of the Linux kernel designed to prevent a system from crashing when it runs out of available memory. When the kernel detects a severe memory shortage, it invokes the OOM Killer to reclaim memory by terminating one or more processes. This is […]

Dockerizing and Orchestrating Legacy C++ Systems on Modern AWS Infrastructure

Assessing Legacy C++ Application Dependencies Before embarking on containerization, a thorough audit of the legacy C++ application’s dependencies is paramount. This involves identifying all external libraries (static and dynamic), system-level utilities, configuration files, and any runtime requirements. For C++ applications, this often includes specific compiler versions, build tools (like CMake, Make), and potentially older versions […]

Fixing Deadlocks on InnoDB row-level locking during simultaneous checkout writes in Legacy Laravel Codebases Without Breaking API Contracts

Diagnosing InnoDB Row-Level Lock Contention in High-Concurrency Writes Legacy e-commerce platforms, particularly those built on older Laravel versions and relying on MySQL’s InnoDB engine, often encounter insidious deadlocks during peak traffic events. These deadlocks typically manifest during simultaneous checkout operations where multiple requests attempt to modify the same set of inventory or order-related records. The […]
