In our project, we register CRON jobs using RegisterPeriodicTask. The CRON jobs are configured with the timezone Asia/Tokyo. We have registered 5 CRON jobs, and the job scheduled for 1:00 AM JST was not executed on certain days. Below are the details:

January 8, 2025:
12:00 AM JST: Executed successfully.
12:15 AM JST: Executed successfully.
12:30 AM JST: Executed successfully.
1:00 AM JST: Did not execute.
1:30 AM JST: Executed successfully.

January 11, 2025:
The same issue occurred where the 1:00 AM JST job did not execute.

Note : All other CRON jobs executed successfully on these days.

Architecture

  • We use a Machinery worker with Redis configuration.
  • The Golang image is deployed in ECS with a task desired count of 2.
  • Both ECS tasks register the CRON jobs.

Could you please help me to find the cause and solution?
