Scheduled agent sometimes runs sometimes not

Hi! In the production server that has heavy load, we found some scheduled agents are not running sometimes.

Scenario:

  • an agent scheduled to run every 30 minutes

  • the agent has been in production for a long time, without any changes. So far it only takes request (based on availability of certain documents) and launch some Java codes.

When I checked the ths agent’s log at 12 noon, it showed that the last run was at 9:30am. Also the server was running fine without any crashes.

But how come the agent never ran from 9:30am to 12:00pm, which it should run every 30 minutes?

Anyone can shed some light here? TQ!
