I finally got the dummy program working. There were several issues:
- event_buffer_size was defined as 10000 * 32 MB = 320 GB, exceeding the RAM of the computer

The problem has been fixed on commit 825935dc on Oct. 2021 and runs fine since then at PSI. If TRIUMF people
agree, we can close that issue and proceed.

Thanks for the answer.
As soon as I can(possible in a month) I'll try suggestion below:

I just came back to this and started to use the dummy frontend.
Unfortunately, I have a problem during run cycles:

What you describe is a well-known problem with the ODB. At PSI we have similar issues. There are
two approaches to solve it:

One idea: we should have a look at mlogger::close_channels(). There the SYSTEM buffer is emptied through the cm_yield() call. Instrumenting this with some
debugging code will enlighten us.
