Terminate called after throwing an instance of 'std::runtime_error' what(): Response timed out

Connecting a Kepware server after some times the program is aborted with the error in the title. I am using the subscription method.
Observing the frame stack with gdb I detected the following once the exception is thrown:

Changing the function void KeepAliveThread::Run() as in the following the issue appears solved.
