We have two reports for Financial department that is scheduled as Task to run every morning 6am in Production. For the last 3 days, these tasks are not getting triggered. We are manually running the reports and sending it to the user. The ScheduledTaskProcessor agent is running fine without any exceptions. Node health is good, but we can observe the "Hazelcast not active" messages in the broken queue items for the Scheduled Task Processor. Any insights to fix this will be helpful.
