C# Web API 错误：套接字连接已中止

如何解决C# Web API 错误：套接字连接已中止

我正在使用 C# Web API 在 power automatic 和 AX 2012 之间进行集成。我每隔一段时间运行一次流就会收到这个临时错误。

下面是控制器的 C# 代码

public class MainController : ApiController
    {
        [ActionName("Method")]
        [HttpPost]
        [Authorize]
        public IHttpActionResult CallMethod(ClassMethodCallRequest request)
        {
            dynamic retValue;
            bool success = false;
            AX2012.SXAFlowIntegrationServiceClient client = null;        

            try
            {
                client = new AX2012.SXAFlowIntegrationServiceClient();

                var callContext = new AX2012.CallContext();
                callContext.Company = request.companyId;
                callContext.logonAsUser = User.Identity.Name;

                client.InnerChannel.OperationTimeout = new TimeSpan(0,10,00);
                client.Endpoint.Address = new System.ServiceModel.EndpointAddress(request.aifURL);

                retValue = client.callMethod(callContext,request.className,request.methodName,request.dataJsonStr);
                client.Close();
                success = true;

            }
            catch (Exception e)
            {
                return Json(new ClassMethodCallResponse
                {
                    status = "Error",userName = User.Identity.Name,className = request.className,methodName = request.methodName,aifURL = request.aifURL,error = e
                });
            }
            finally
            {
                if (!success)
                {
                    client.Abort();
                }
            }
            
            return Json(new ClassMethodCallResponse
            {
                status = "Success",data = retValue,});
        }

    }

这个问题迫使重新提交一个漫长的过程。第二次运行后不会弹出错误，但如果我在一段时间后再次运行流程，则会再次抛出错误。

错误是否与超时有关？我没有找到此错误的根本原因。
