5 Second interval batch job did not run

Hello SAP Experts,

Good day to you. We have a custom program in Production and we set it

to

run in a 5 second interval. We also added a trigger program in the step

so that once the job finishes, the job will run again without delay. I

attached a screenshot of the steps of the job

The job then suddenly stopped one time and did not run for 4 hours. We

had to manually run it for the job to run. May I know what might have

caused this? Is it feasible in SRM to schedule a job with just a 5

second

interval?

Regards.
