We had recently some problems at our experiment which I would like to share
with the community. This affects however only experiments which have a slow
control front-end in multi-threaded mode.

Hello there,
in our setup we use many variables with many different exceptions. Would it be possible to implement something like an
IF or/and IF statement? I believe that this is currently not possible.

The tinyexpr library I use to evaluate expressions does not support boolean operations. I would have to switch to the newer
tineyexpr-plusplus version, which also has much richer functionality:

The ODB server seems to have crashed/corrupted. I tried reloading the previous
working version of ODB(using the commands in folliwng image) but it didn't work.

For our MIDAS installation at Fermilab, it is necessary that we be able to write to a PosgresQL
database (MySQL is not supported here). This will be required of both mlogger and mscb.

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:

I have seen the same behaviour and it annoys me, too. What I did in the past
