The frame builder (or something) is unhappy again. I know that we've seen this before, but I can't find the elog entry that relates to this particular problem.
Every few minutes, the fb status lights on the CDS_STATUS screen go white, and then come back green. It's annoying when it happens every hour or so (which is unfortunately typical), but it's pretty debilitating when it stops dataviewer and dtt every few minutes. Just from the way the lights change, it looks like perhaps the daqd process is restarting itself periodically?
