Have you updated to the current midas version? This issue has been fixed a while ago. Below

I guess you won't change your FPGA configuration just when you start a run, so I don't consider the race
condition very crucial (although KO is correct, it it there).

For ODB keys of type TID_KEY, the value num_values IS the number of subkeys. The only issue here is
