Cleanly close the boost socket and thread?

I have a problem while closing the client app, when server is closed.
I have my read thread and a class which implements tcp connection.
Code is below:

This is in my main file - main.cpp

void thread_handling()
{
	/*
	 * Start threading only if server is connected, if not connected Exit Jupiter App
	 */
	if(g_serverconnected)
	{
		/*
		 * Start a thread for reading through TCP socket continuously
		 */
		boost::thread workerThread1((boost::bind(&TCP::RcvData_sck,g_Client));

		/*
		 * #TODO: Shutdown
		 */

		workerThread1.join();
	}
}

TCP.cpp

int TCP::RcvData_sck()
{

	boost::system::error_code e;
	int length;
	try
	{
		for (;;)
		{
			/*
			 *read_some() -  This function is used to read data from the stream socket.
			 * The function call will block until one or more bytes of data has been read successfully, or until an error occurs.
			 * The number of bytes read is returned. Returns 0 if an error occurred.
			 */
			length=m_Socket.read_some(boost::asio::buffer(m_RecieveBuffer),e);
			if(e)
				throw boost::system::system_error(e);
			/*
			 * copy received data to Vector
			 * Dynamic buffer to handle incoming data as length of received data may vary
			 */
			std::vector<uint8_t>buffer_read_notify;
			for(int i=0;i<length;i++)
			{
				buffer_read_notify.push_back(m_RecieveBuffer[i]);
			}

			if(length>0)
			{
				memset(m_RecieveBuffer,m_BufLen,0);
				//process data
			}
			buffer_read_notify.resize(0);
			m_IOService.run();

			if(e==boost::asio::error::eof) //connection closed by router
				{
					std::cout<<"connection closed by router";
					g_serverconnected = false;
					m_IOService.stop();
                        m_Socket.close()
					break;
				}

			m_IOService.reset();
		}
	}
	catch (std::exception& e)
	{
		
		g_serverconnected = false;
		m_IOService.stop();
                m_Socket.close()
		return 0;
	}
}

But I am stuck in a scenario where server ends the connection.
I receive exception : "An existing connection was forcibly closed by the remote host".
My threading part is in different file which is out of scope of class.
I want is to join thread when ever I get the exception.
How do I achieve this?
Any help or tip to guide will be much appreciated.

What I have tried:

I have tried keeping try-catch block within my for loop of read and break whenever exception is found, but it didn't work.

Also, I tried return 0 for the function when exception arrives based on which I will join the thread to main process but not sure how to evaluate it in thread_handling() function.If some one can explain that also,then it would be really helpful.
