    • The present invention is directed to detecting leaks in computer memory. Memory leaks are detected by analyzing computer component memory usage records. The first derivative of the memory usage data is computed. If the area under a curve created by a plot of the first derivative of the memory usage data is greater than zero, the second derivative of the memory usage data is computed. If the area under a curve created by a plot of the second derivative of the memory usage data also is greater than or equal to zero, the memory usage data is analyzed to determine how many minima points are present in the memory usage data. If less than four memory usage data minima points are present, a memory leak exists. If four or more minima points are present in the memory usage data, the minima points are further processed to determine if a memory leak exists.
    • 本发明涉及检测计算机存储器中的泄漏。 通过分析计算机组件内存使用记录来检测内存泄漏。 计算内存使用数据的一阶导数。 如果由存储器使用数据的一阶导数的曲线创建的曲线下的面积大于零,则计算存储器使用数据的二阶导数。 如果通过存储器使用数据的二次导数的曲线创建的曲线下的面积也大于或等于零,则分析存储器使用数据以确定存储器使用数据中存在多少个最小点。 如果存在少于四个内存使用量数据最小点,则存在内存泄漏。 如果存储器使用数据中存在四个或更多个最小点,则进一步处理最小点以确定是否存在存储器泄漏。
