Embodiment Construction
[0044] The present invention is a runtime memory leak detection method oriented to the Xen virtualization environment, such as Image 6 As shown, including the following steps:
[0045] Step 1: Dynamically analyze the memory usage behavior of the monitored program, group the memory objects according to the different events of the memory objects or other grouping principles to form multiple memory object groups, and maintain and update the relevant information of each memory object group; The memory object refers to a memory block allocated by system calls such as malloc, realloc, calloc, etc.; the memory object lifetime refers to the period of time from when the memory object is allocated to being released, the lifetime of the memory object is taken The value is in an open interval (0,∞) in a mathematical sense; the memory object group refers to a collection of memory objects with a certain commonality, and each memory object is represented by a tuple (size, callChain), size rep...
