Debugging Slow Servers with Strace and Ltrace

When your Linux web server stalls for five seconds on every other request, where do you start? This episode walks through a real debugging session using strace and ltrace to uncover a hidden file-lock bottleneck. Lucas and Luna trace system calls and library calls in real time, showing how a single read operation on a shared config file turned a fast Nginx server into a crawl. You'll learn the practical difference between strace's -p and -c flags, how to read call output without drowning in data, and when ltrace's library-level view reveals what strace misses. By the end, you'll have a repeatable process for attaching to a misbehaving process, filtering the noise, and pinpointing the exact kernel interaction causing the delay. Perfect for sysadmins who manage production Linux servers and want to retire the guess-and-reboot workflow.
