On running with debug flag, I see:
[2023-05-01 05:08:30] [loader.py] DEBUG: currently existing job stream has different 'mem' than the definition
Issue appears to be that jobs.yml defines mem, whereas /list API output contains memory. The normalisation applied in code seems to be the other way round.
