SDB2 timing issues and dbox reconfiguration

Today I reconfigured the 4 DAQ boxes of SDB2 in order to solve timing issues resulting from our intervention on the bench.

The reconfiguration took place between 21h59 and 22h03 utc.

The Timing flag in the DMS is back to green, however, since the reconfiguration the processes SDB2_Photodiodes, SDB2_Quadrants and SDB2_Readout seem to be misbehaving. A DAQ expert has been informed;

All the SDB2 DBoxes wer reconfigured but without any improvments . 

As trial the output of  the B5_QD1 and B5_QD2 demodulation  sample data were commented and  in these conditions , all the data were correctly received by the  SDB2_Photodiodes, SDB2_Quadrants and SDB2_Readout  servers.

To restore all the SDB2  demodulation sample data, for all the demodulation sample output packets  the output frequency is now set to 2kHz instead of 5kHz with 16 words of 32bits.
