    keyword=Often Compton DAQ crashes

    Compton DAQ crashes a lot lately (once per shift or so). Rates become constant in the stripchart. Looking at the rocs, ROC1 and ROC2 die like shown below. I once got this kind of message when the rates were too high due to a very bad beam, but the beam looks ok today and rates are reasonable. I guess Sirish need to look into it.

    BTW, the golden recipe (coda reboot/coda start) works to bring the DAQ up again.
