No, I'm not aware of this problem, but I suspect that your events somehow got corrupted. You can try the mdump utility
or the "Event Dump" web page to peek into your events, maybe you see an issue there. To give you more detailed information,
I would have to reproduce your problem, which is probably hard without your hardware.

Good morning,
In our setup, we have a neutron detector that creates up to 16 MB of polled (EQ_POLLED) data in one event (event limit = 1) that we do not want to have |

I cannot confirm that. I just tried myself with examples/experiment/frontend.cxx, removed the RO_ODB, and the trigger events did NOT get copied to the ODB.
Actually you can debug the code yourself. The relevant line is in mfe.cxx:2075:

Dear MIDAQ developers,
I wonder if there is a non-intrusive way to have an external (wrt MIDAS)*SQL database

I have one more question, though I understand that it could be somewhat border-line.
The MIDAS state machine doesn't seem to have a state in between 'initialized' and

to plot time dependencies of the monitored detector parameters, say, voltages or temperatures,
one needs to convert the coresponging ADC readings into floats.
