Box has Missed the Run Window when the start time matches the end of the run_window.
In the job defintion we mention the run window where the job you are defining may start.
But when the job executes the CHK_RUN_WINDOW checks for the end time "20:30" and marks the job as inactive if it starts at the exact same time.
[11/09/2015 20:30:04] CAUAJM_I_40245 EVENT: CHK_RUN_WINDOW JOB: xxxxx
[11/09/2015 20:30:36] CAUAJM_I_40245 EVENT: CHANGE_STATUS STATUS: INACTIVE JOB: xxxxx
[11/09/2015 20:30:36] <Not run today - Missed the Run Window>
The problem has been fixed in 11.3 SP1 Incr4
The patched scheduler schedules a job with the run_window it is supposed to generate a CHK_RUN_WINDOW event *one minute* after the end of the run_window.
So if the end of the run window is 20:30, the patched scheduler is supposed to generate a CHK_RUN_WINDOW event for 20:31, not 20:30. The scheduler does not evaluate a job to run when the CHK_RUN_WINDOW event is processed because by then, the job is truly beyond the run window.
