Thanks for the investigation. Back in 2020, we had some issues of losing data between the system buffer and the logger writing them to disk (https://daq00.triumf.ca/elog-midas/Midas/1966). This was polled equipment but we had a multithreaded FE running at the same time. Could this be related to the same problem?

Best, Ivo
