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, among other things. Instead of taking a theoretical route, you will focus on hands-on lessons on a variety of memory analysis patterns found in 64-bit core memory dumps from the x64 architecture. You will follow the novel pattern-oriented diagnostic analysis approach that considerably helps with the analysis. Moreover, the course will provide you with problematic applications and the associated core dumps, along with brief descriptions of relevant patterns and some frequently asked questions.

"You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it."
