Abstract

The present invention provides a method for locating message memory leaks, the method comprising: setting a first flag bit for indicating whether the message memory is occupied and a second flag for indicating the message processing stage in the message header bit, and hang all messages on a linked list; when a message memory leak occurs, traverse the linked list to obtain the first flag and the second flag of all messages; find out the memory by the value of the first flag Occupied messages; count the value of the second flag bit of all messages whose memory is occupied, and find out the value of the second flag bit that occurs most frequently; find the corresponding message according to the value of the second flag bit that occurs most frequently The processing stage is where the packet memory leaks. The invention can narrow down the scope of the problem in a short time, thereby achieving the purpose of quickly locating message memory leaks.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method for locating message memory leaks. Background technique [0002] The processing of network packets is the basis of network devices. When the hardware such as the network card of the network device receives a message, it will save the message in a pre-allocated memory, and the CPU in the network device will obtain the content of the message in the memory, and analyze and process the content of the message , and send or discard the message according to the processing result. No matter whether the message is finally sent or discarded, the memory corresponding to the message will be released, otherwise it will cause a memory leak. When a memory leak occurs, the hardware of the network card cannot store the network packets in the memory because the memory cannot be applied for, the CPU cannot receive the packets, and the entire network device cannot work. [0003] Because...
