Regarding delay in Designer to generate the file

Hello Team,

We have put the schedules to generate some files at specific time but its failing sometimes to generate the file .

for eg . if we have schedules at 4:40 AM to generate file then because of some reasons its either not creating the file or there are some delays upto 9 hours from schedule timings in generating the file.

So please let me know what action we should take in this case.
