   In this issue, airflow doesn't create runs for the whole days/runs - it acts 
like the dag is disabled and skips days/runs.
   
   I **think** that might still be related. Simply some subtle bug (like 
running the schedule precisely at the very moment it should be scheduled) might 
trigger it. For some reason you seem to have an installation where this 
behaviour seems to be easily reproducible, so maybe we can use it to narrow 
down the issue.
   
   I think @hussein-awala  was right it would be great if you could try to 
reproduce it with old expression and catchup = False. From what I understand 
above, `catchup =True` actully solves the problem. If we could know that also 
the old schedule does (independently from catchup = True), it could help to 
narrrow down the issue.
   
   Also cc: @uranusjr -> It really looks like some edge-case i 
CronTriggerTimetable from the description and helpful experiments done by 
@ibardarov-fms . The 14 seconds delay in queue time shows that likely there 
might be a race condition that gets triggered somewhere by the timetable.
