  • Probing into Core Dumps with mdb

    Posted August 12, 2009 - 2:19 pm

    The Solaris Modular Debugger (mdb) is a debugger that was designed for low-level debugging -- examining the running kernel or looking into core files and using assembly language know how to figure out what was happening at the time of a system crash. Core dumps are similar in concept to the flight recorders on commercial airplanes. Because they contain the contents of memory at the time of the crash, you can ask just about question you might want to ask about that fatal system moment, but you have to be a very savvy systems geek to know what questions to ask and to understand the answers.
