 ### Restart Data Retrieval
 If there are issues with data retrieval (DataBuffer, ImageBuffer, Epics Channel Archiver) but all checks regarding the DataBuffer shows normal operation use this procedure to restart the SwissFEL data retrieval services. This will only affect the data retrieval of SwissFEL at the time of restart but there will be no interrupt in the recording of the data.
