UNSOLVED (1MHz): when we record 10 hsd's to disk disable times out for several segment levels.  No errors in logfiles.  Timeouts too short for 1MHz?

UNSOLVED: hsd configure times out the first time, but works second time.  Matt says that he seen the transition not received at all by the hsd.  Phase 1 completes in Digitizer.cc but phase2 maybe doesn't start, consistent with Matt's observation?  log file in /reg/neh/home/cpo/2020/06/12_17:41:55_drp-tst-dev010:tmohsd_0.log.  What I observed: both tmohsd_0/1 completed phase 1 but failed to receive phase 2.  How I think it's supposed to work:  tmohsd_0/1 each write some kcu registers (resetting tx/rx/user/qpll).  both tmohsd_0/1 set config epics vars in its own pva server ("hsdpvs" process).  both of these servers communicate with one "hsdioc" (running hsd134PVs c++ executable on dev07).  hsdioc programs both channels of the hsd ("fmc" in the code) and sets READY (e.g. DAQ:LAB2:HSD:DEV07_1A:B:READY).  tmohsd_0/1 both watch for their own A:READY and B:READY for each channel.  maybe resets take a while to recover?  maybe a "reentrancy" problem in hsdioc?Could it be the clear readout?  But we have a 1s delay in control.py after clear readout (sent on both configure/beginrun).
