Iam using qtcreator 5, Database mongodb(mongocxx) . Below code is placed inside a loop ,loop works when there is data available in socket .Data reads fast from socket, when i put mongodb insertion code here it makes builded application not responding ,But the data is sending to mongodb without any problem.

Data can be see in Qt creater editor ..only the builded application cannot access (not responding ).

How to fix it????

code part:

in header file:
     mongocxx::client& conn1 = get_client();
     mongocxx::database db;
     db = conn1["ASSET_TRACKING"];

in Loop:
         if (k != -1)
                    {
                     // qDebug() << "value found at "<<k ;
    
                     qWarning("Got db conn");
    
                    switch(k)
                    {
                      case 0 :
                      {
                         std::vector<bsoncxx::document::value> documents;
                         documents.push_back(
                         bsoncxx::builder::stream::document{} <<"tag_ID"<< e.toStdString() <<"POSX"<<posx<<"POSY"<<posy<<"POSZ"<<posz<< finalize);
                         db["Tagdemo"].insert_many(documents);
