<p>Hello all,</p>
<p>Many thanks to Wassim, Christine, Yaopeng, Hao and Mark for signing up for shift for next week.<br />
We still have unassigned shifts on Monday Apr 8 and Wednesday Apr 10.</p>
<p>RC summary:<br />
* Taking production data whole day yesterday April 5-th without any major interruptions.<br />
* 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 <a href="https://logbooks.jlab.org/entry/4274916">https://logbooks.jlab.org/entry/4274916</a><br />
* 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, <a href="https://logbooks.jlab.org/entry/4274920">https://logbooks.jlab.org/entry/4274920</a><br />
* Most likely the issue is in the replay program<br />
* 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<br />
* 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.<br />
* Many thanks to Casey Morean, who called back to the counting house very early in the morning, and is currently working on fixing it.</p>
<p>* The meeting with MCC and Halls just finished, and currently the estimate for Hall-A to be back is Thursday.<br />
* 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.</p>
