Hello everyone,
`int main(int argc, char** argv)
{

    int a = 0;
    OpcUa::UaClient* client = new OpcUa::UaClient();
   
    client->Connect("opc.tcp://127.0.0.1:49320");

    OpcTransaction Transaction(client,
        std::string("ns=2;s=Channel2.Device1.Global.AAA_Trigger"),
        std::string("ns=2;s=Channel2.Device1.Global.AAA_Ack"));

    Transaction.TransactionTags.push_back(TransactionTag(std::string("ns=2;s=Channel2.Device1.Global.AAA_DINT"), 1));
    Transaction.TransactionTags.push_back(TransactionTag(std::string("ns=2;s=Channel2.Device1.Global.AAA_BOOL"), 2));
    Transaction.TransactionTags.push_back(TransactionTag(std::string("ns=2;s=Channel2.Device1.Global.AAA_REAL"), 3));

    OpcTransactionHandler THandler(&Transaction);

    THandler.start();

    OpcTransaction Transaction1(client,
        std::string("ns=2;s=Channel2.Device1.Global.BBB_Trigger"),
        std::string("ns=2;s=Channel2.Device1.Global.BBB_Ack"));

    Transaction1.TransactionTags.push_back(TransactionTag(std::string("ns=2;s=Channel2.Device1.Global.BBB_DINT"), 1));
    Transaction1.TransactionTags.push_back(TransactionTag(std::string("ns=2;s=Channel2.Device1.Global.BBB_BOOL"), 2));
    Transaction1.TransactionTags.push_back(TransactionTag(std::string("ns=2;s=Channel2.Device1.Global.BBB_REAL"), 3));

    OpcTransactionHandler THandler1(&Transaction1);

    THandler1.start();
    
   // std::this_thread::sleep_for(std::chrono::seconds(600));
    
    for (int i = 0;i < 200;i++) {

        
        std::this_thread::sleep_for(std::chrono::seconds(10));
        Node aa = client->GetNode("ns=2;s=Channel2.Device1.Prgm_AOI_TEST.ByteDataBuffer_index");
        CheckStatusCode(aa.GetAttribute(AttributeId::Value).Status);
        std::cout << aa.GetDataValue().Value.ToString() <<"\t"<< aa.GetAttribute(AttributeId::Value).Status << std::endl;

    }

    std::cout << "exiting" << std::endl;
    THandler.stop();
    client->Disconnect();

}`
This is my client code. When i run my program, "KeepAliveThread stopped" after 2-3 minutes. I don't understand why am i get this error. Can anyone help me for issue.
Thank you.

Hi,
I think your problem is the bug I describded issue #410 Race condition between "send request" and "receive response" threads.

The fix I proposed works for me.
