Sent email to Michael Davidsaver, Hugo Slepicka and the control group to see if they had seen this before.  They had not.  Michael wrote:  "At a guess, a
client disconnect will be involved."  Michael wrote back later that he found a race condition that could explain it.  Will be addressed in a future release.

 

(diagnostic) UNSOLVED: Possibly the same issue as above, but this time with hsdpva.  See ~claus/2020/08/27_10:34:36_daq-tst-dev02:hsdpva.log.

(diagnostic) UNSOLVED: according to hsdpva only one hsd was producing dead time (due to msgdelay being set too short) but xpmpva showed all hsd's having dead time.  at other times xpmpva seems to be attributing dead time correctly, so it's somehow an intermittent issue, perhaps only happening when Ben detects his front-end buffers have overflowed?  (which causes him to latch dead time until receiving clear readout).
