After running for a while, the C project calls the C# WCF interface and an Out of memory Exception occurs

Question

After running for a period of time, Out of memory Exception occurs when C++ project calls C# WCF interface.
WCF Client:
NetTcpBinding Bindings = new NetTcpBinding();
Bindings.Security.Mode = SecurityMode.None;
Bindings.MaxReceivedMessageSize = 2147483647;

ChannelFactory<MyWCFClient> myWCFFactory = new ChannelFactory<MyWCFClient>(Bindings, serverAddress);
If(myWCFFactory == null)
return;
MyWCFClient channel = myWCFFactory.CreateChannel();
If(channel == null)
return;
try
{
switch(((IClientChannel)channel).State)
{
case CommunicationState.Faulted:
((IClientChannel)channel).Abort();
channel = myWCFFactory.CreateChannel();
((IClientChannel)channel).Open();
break;
case CommunicationState.Opened:
break;
case CommunicationState.Closed:
channel = myWCFFactory.CreateChannel();
((IClientChannel)channel).Open();
break;
case CommunicationState.Created:
((IClientChannel)channel).Open();
break;
default:
((IClientChannel)channel).Abort();
channel = null;
break;
}
}
catch
{
}

WCF Service:

static ServiceHost myServiceHost = new ServiceHost(….);
NetTcpBinding Bindings = new NetTcpBinding();
Bindings.CloseTimeout = TimeSpan.Parse(“00:01:00”);
Bindings.OpenTimeout = TimeSpan.Parse(“00:01:00”);
Bindings.ReceiveTimeout = TimeSpan.Parse(“00:01:00”);
Bindings.SendTimeout = TimeSpan.Parse(“00:01:00”);
Bindings.TransactionFlow = false;
Bindings.TransferMode = TransferMode.Buffered.
Bindings.MaxBufferPoolSize = 1024;
Bindings.MaxBufferSize = 1073741824;
Bindings.MaxReceivedMessageSize = 1073741824;
Bindings.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard;
Bindings.ReaderQuotas.MaxDepth = 64;
Bindings.ReaderQuotas.MaxArrayLength = 2147483647;
Bindings.ReaderQuotas.MaxStringContentLength = 2147483647;
Bindings.ReaderQuotas.MaxNameTableCharCount = 2147483647;
Bindings.ReaderQuotas.MaxBytesPerRead = 2147483647;
Bindings.ReliableSession.InactivityTimeout = TimeSpan.Parse(“00:01:00”);
Bindings.ReliableSession.Ordered = true;
Bindings.ReliableSession.Enabled = false;
Bindings.Security.Mode = SecurityMode.None;

myServiceHost.AddServiceEndPoint(…,Bindings,….);

Is there any configuration error?
In the interface where the error occurs, the length of the parameter is a fixed value, which is a string of GUID strings, so it is unclear what caused it.

Hello,

Welcome to Microsoft Q&A!

Currently, Microsoft Q&A supports the products listed over here: supported topics (more to be added later on).

Your question about WCF is not supported yet now. You could ask about this in the Windows Communication Foundation, Serialization, and Networking forum.

Thank you.
