Call to Rest API does not return on Centos7

[dheeraj12190]

Hi
Below is my function this works file for ubuntu and rhel but when it come to centos,
and I make a call to this function it does not return and stuck in between.

bool CSchedule::getSchedule(vector<StSchedule> &MeterSchedule)
{
	bool bRetVal = false; 
	try
	{
		// Create and instantiate a Post from data received from the server.		
		cout << endl << "in getSchedule:" << sAddress << endl;
		MeterSchedule =  RestClient::Create()->ProcessWithPromiseT<vector<StSchedule>>([&](Context& ctx) {
			// This is a lambda co-routine, running in a worker-thread
			// Instantiate a Post structure.
			vector<StSchedule> t;
			// Serialize it asynchronously. The asynchronously part does not really matter
			// here, but it may if you receive huge data structures.
			SerializeFromJson(t,
				// Construct a request to the server
				RequestBuilder(ctx)
					.Get(sAddress)
					// Add some headers for good taste
					//.Header("X-Client", "RESTC_CPP")
					//.Header("X-Client-Purpose", "Testing")
					.DisableCompression()
					.Argument("MeterNo",this->sMeterNo)
					// Send the request
					.Execute());
			// Return the Post instance trough a C++ future<>
			return t;
		}).get();
		bRetVal = true;
	}	
	catch (exception &e)
	{
		LOG(ERROR) << "<<Exception Caught in getSchedule for Meter Serial Number:" << this->sMeterNo << ":" << e.what();
	}
	return bRetVal;
}

Can you step trough with the debugger to determine where it locks up?

[dheeraj12190]

it goes into multiples steps in. after that it hits below line several times

boost::asio::detail::scoped_ptr<boost::asio::detail::strand_service::strand_impl>::scoped_ptr (this=0xb57c18, p=0x0)

32          : p_(p)

and then comes out from this after that it prints

I'll have to try to reproduce it.
Have you built it with stock centos7, or have you installed newer compiler/boost?

[dheeraj12190]

I have installed new one
