We have upgraded the Domino server to 6.5.1. After this a weekly schediled agent was not running during its scheduled time. If it was set to run after 1 hour from the current time, it was running. But it was a agent to be run once a week(Friday 4PM). The Agent was Enabled and the signer of the code was also admin. What may be the reason for the above problem? Expecting the solution as early as possible.
