Scheduled Task not triggering on time in InterSystems IRIS

Question

Rovmen paul · Jul 9

Hi everyone,

I’ve set up a scheduled task in InterSystems IRIS to run every night at 2:00 AM, but it doesn’t seem to trigger consistently. Some nights it works as expected, but other times it just skips without any error in the logs.

The task is marked as enabled, and there are no conflicts in the Task Manager. I’ve double-checked the system time and time zone settings all looks fine.

Could it be a cache issue or something to do with system load?

Thanks!

Screenshots would certainly help, and an explanation of what the task actually does would help as well (Is it a backup, does it export data to a different system, wash the dishes maybe? :-) ). Is it possible that the task may at times take longer than 24 hours to execute? I have seen instances where a process 'hangs' so TaskMan thinks it's still running and doesn't fire up a new instance of that task.

Hope this helps!
