Strange. RPC seems to be working, otherwise the initial check on startup would have failed. And in nuffsaid420's case MSC transactions were recognized which indicates a RPC connection as well as valid transaction fetching and parsing. When and how often does the exception occure? Several hundred times or only from now and then? Are "simple send" transactions the only ones found?
