Every computer user is familiar with software bugs. Many seem to appear almost randomly, suggesting that the conditions triggering them must be complex, and some famous software bugs have been traced to highly unusual combinations of conditions. For example, the 1997 Mars Pathfinder mission began experiencing system resets at seemingly unpredictable times soon after it landed and began collecting data. Fortunately, engineers were able to deduce and correct the problem, which occurred only when (1) a particular type of data was being collected and (2) intermediate priority tasks exceeded a certain load, allowing a blocking condition that eventually triggered a reset.
