Course Overview

It’s essential to examine core dumps to diagnose any non-trivial hangs or crashes due to a user process or the kernel faults. Most people have no training in dealing with core dumps, so the causes of most crashes remain undiagnosed. This course starts with debugging core dumps. You will learn how to debug the Linux process and kernel failures (using the GDB debugger and the crash utility), browse core memory dumps, identify corruption, memory leaks, CPU spikes, halted threads, deadlocks and wait chains, am...Show More
