• Getting Broken Pipe error while communicating with Mobile Application. We have an existing problem where our Test(Test bank Mobile Broker) services are not responding to DataGrid call. Getting the above ERROR in the DataGrid logs. This Error in DataGrid is coming after a period of almost 10 minutes from our Test services issue. This issue is getting resolved when we are restarting our services but we are keen to understand what this Broken pipe error indicates in DataGrid?
