STL alternative for memory leak

I am very new bee to C++ coding and STL library usage. I was quite interested on using STL library on my C++ program which I was developing. But recently I tried using Visual Leak detector and found many leaks which are specifically where ever I used STL library and new operator.

Since it is an runtime application I also found the CPU memory keeps increasing when I run the code for 4-5 days continuously. Learning on some of the forums and other noted, I understood that I need to delete/erase the content inside the std::map, std::unordered_map, std:set before calling its corresponding clear. My question here is if I do all those on the destructor calls which are never gonna called (since my programmer never going to STOP) will the STL library create memory leak every time I access it?

Is there an alternative for this?

Example: common.h

struct stTagElem_t {
    uint32_t  m_unOffset;
    uint32_t  m_unArraySize;
    string    m_acTagName;
    string    m_acTagValue;
    string    m_acDataType;
} ;

typedef std::unordered_map<uint8_t, stTagElem_t> tagsList_t;

struct stMappingElem_t {
    uint16_t     m_unMemSize;
    tagsList_t   m_stTagsList;
    string       m_acEventName;
    string       m_acMapTypeName;
} ;

typedef std::unordered_map<uint32_t, stMappingElem_t> eventDataMap_t;

dataMapManager.cpp //declared as global list since dataMapManager.cpp has all static functions

eventDataMap_t sm_eventDataMapList;

So When I use Visual Leak Detector It says the following:
