MS家的工具还是可以的。UMDH的diff输出里，排名第一的基本就是leak点。

起因是端口被人占了，然后反复开socket尝试bind端口，反复泄漏socket。"占坑攻击"

// Each log entry has the following syntax:                                
//                                                                          
// + BYTES_DELTA (NEW_BYTES - OLD_BYTES) NEW_COUNT allocs BackTrace TRACEID
// + COUNT_DELTA (NEW_COUNT - OLD_COUNT) BackTrace TRACEID allocations      
//     ... stack trace ...                                                  
//                                                                          
// where:                                                                  
//                                                                          
//     BYTES_DELTA - increase in bytes between before and after log        
//     NEW_BYTES - bytes in after log                                      
//     OLD_BYTES - bytes in before log                                      
//     COUNT_DELTA - increase in allocations between before and after log  
//     NEW_COUNT - number of allocations in after log                      
//     OLD_COUNT - number of allocations in before log                      
//     TRACEID - decimal index of the stack trace in the trace database    
//         (can be used to search for allocation instances in the original  
//         UMDH logs).                                                      
//

回头试试。我习惯用vld

【 在 speedboy2998 的大作中提到: 】
: VS 已经集成了 Sanitizers，用起来很方便，可以试试。
