Weird problem where two GDS channels can't be read together
From nds.ligo-wa.caltech.edu: two gds channels, H1:GDS-CALIB_STRAIN, and H1:GDS-CALIB_STRAIN_NOLINES cause a time_out reading from nds2 when read together and looking at past data.
- when read individually, it works
- when read from live data, it works
- when read together on past data with a third channel from the DAQ, e.g.
H1:OMC-FPGA_DTONE_IN1_DQ
, it works.
