Hello all,

Many thanks to Wassim, Christine, Yaopeng, Hao and Mark for signing up for shift for next week.
We still have unassigned shifts on Monday Apr 8 and Wednesday Apr 10.

RC summary:
* Taking production data whole day yesterday April 5-th without any major interruptions.
* Today during the owl shift around 2 am DAQ crashed, then after fixing it, shift crew noticed that replay plots are empty, some details are in the log entry https://logbooks.jlab.org/entry/4274916
* Contacted Bob Michaels, he took a look into DAQ, didn't find any issue with the DAQ, No error messages, files are being written and banks are present, https://logbooks.jlab.org/entry/4274920
* Most likely the issue is in the replay program
* Later doing some more debugging, it turned out that indeed it is the replay, as running it over previously "Good" runs, now it shows empty histograms
* VTP scalers, and calorimeter anode currents all look normal. Given that we don't see a real evidence that the raw data is bad, we decided to continue the data taking without the replay, and try to fix it as soon as possible.
* Many thanks to Casey Morean, who called back to the counting house very early in the morning, and is currently working on fixing it.

* The meeting with MCC and Halls just finished, and currently the estimate for Hall-A to be back is Thursday.
* There are some minor issues with the Accelerator, but they are hopeful that they can hold those works till the time when Hall-A will be back, so if everything goes well we don't expect beam interruptions till Thursday.
