This morning 20190529-06h16m00UTC, all the data were lost at the FbmAlp level  during 10s

Here the content of the FbmAlp logfile.

It appears that in the same time period, someone was accessing all the datas directly from the FbmAlp server instead of using the data providers (FbmMoniUsers, FbmDetUsers...) .

As already mentioned the data access on any frameMerger (FbvmFE, FbmMain, FbmAlp, FbmSt, ... ) is reserved to the DAQ expert only and is forbidden during a run.
