After months of running a service using RFA which hits the EZD service, I've run into a new issue that just popped up today. Every minute, I snapshot without update roughly 2600 RICs. After receiving a marketdata event, I attempt to decode a FieldList and get:
An exception of type 'System.AccessViolationException' occurred in RFA8_NET140_x64.dll but was not handled in user code Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
private void DecodeFieldList(FieldList input)
{
if(null == input)return;
var it = new FieldListReadIterator();
it.Start(input); //Exception occurs here
..........
}
In a watch, all FieldList properties show "The metadata for 'RFA8_NET140_x64 is invalid. If you are debugging a minidump,etc...".
I have tracing turned on and I don't see anything that further explains what's happening. Happy to share the logs with a Reuters rep. Eventually after a stream of incoming messages from the box running the EZD app, I just get
<!-- Sending Ping to 'ezdBox:14002' on 'localhost' interface --> <!-- Time: 10:53:47:597 -->
<!-- Ping Received from ezdBox:14002' on 'localhost' interface --> <!-- Time: 10:53:57:598 -->
until I shut down.
