We are using RFA 8.1 C++ api to consume L1 and L2 market data. Lately we have observed that RFA takes considerable time (some times more than 1 min) to close the event after ``unregisterClient` is called. So if you refer below diagram then time lapsed between Event A and Event B is more than 1 minute some times.
This happens randomly. May I know why this can happen? We have been running same RFA application for more than a year now but never faced this issue. Only thing that have changed in last couple of weeks is we enabled Open DACS. I am not sure why this would cause a problem?
