Starting a new night shift - All good

1am full check: 
DSSSD bias &amp; leakage current&nbsp; ok - attachment # 1-2 
FEE64 temperatures&nbsp; ok - attachment # 3 
ADC data item stats - attachment # 4 
Merger ok - Attachement # 5 
Tape service - attachement # 6

2:30am: AIDA02 FEE stopped working. DESPEC main DAQ was alerted and remobe AIDA from timestitcher while I was restarting AIDA DAQ.

2:45am: AIDA02&nbsp; FEE is back and AIDA has been added to the timestitcher again in the main DAQ.

The AIDA runs at the time of the crash to look at are R7_348, 349.

All spectra were zeroed at this time and checked.

4:00 am full check: 
DSSSD bias &amp; leakage current&nbsp; ok - attachment # 7-8 
FEE64 temperatures&nbsp; ok - attachment # 9 
ADC data item stats - attachment # 10 
Merger ok - attachement # 11

6:00am full check:
DSSSD bias &amp; leakage current ok - attachment # 15-16
FEE64 temperatures ok - attachment # 17
ADC data item stats - attachment # 18
Merger ok - attachement # 19

ucesb - attachement # 22

6:30 the nearline/offline analysis team reported possible noise issue in DSSD#2 and asked if the threshold were changed at any point. I can&#39;t find any mention of changes in the elog. 
I&#39;ve not done a setup of the all DAQ when AIDA02 fee crashes earlier this morning. I just did a setup of the merger. Thus I don&#39;t think the threshold have changed when I stopeed and restarted the DAQ.
I can see that currently slow comparator threshod are set to 0xa for most of the DSSD2 fees except for AIDA06 which is set to 0xf. I&#39;m not sure this is the thershold we would need to increase. Something to check during the next shift.</pre>

In the UCESB window I can see that the number of decay in DSSD2 is double the number of decay in DSSD1 while the number of implant is similar. Looking at other shift it looks that this was alsready the case in prvious shifts.
