Several notes on this:

1) The error that is printed out by nanorc is the following:

ERROR    Timeout while waiting for a reply from ruemu0 for command stop

2) To reproduce the issue, you can create a new software area using these instructions (including the download of frames.bin), then run the following commands:

python -m minidaqapp.nanorc.mdapp_multiru_gen --host-ru localhost -d ./frames.bin -o . -s 10 mdapp_4proc
nanorc mdapp_4proc boot init conf start 101 wait 2 resume wait 10 pause wait 2 stop start 102 wait 2 resume wait 10 pause wait 2 stop scrap terminate

This sequence of commands should produce two raw data files, but only the first run produces a data file.

3) I've run tests with various versions of the software, and my sense is that this problem is related to changes in the readout repo. (At first, I thought that the problem was somewhere else). For reference, with tagged v2.6.0 code, I do not see the problem. With the latest readout, dataformats, and dfmessages code and everything else using the v2.6 tag, I do see the problem, so that is why I think that it something to do with readout.
