Apex flex queue
Detect Apex flex queue backlog
Salesforce limits how many asynchronous Apex jobs can sit in Holding status in the Apex flex queue (maximum 100 jobs per org). When that limit is reached, additional queueable or batch work may fail or stall until capacity frees up.
This check counts AsyncApexJob records with Status = 'Holding', including ApexClass.Name, JobType, and CreatedDate for each job, and sends notifications when:
- Warning: the count is greater than or equal to the configured threshold (default 90).
- Error: the count reaches 100 (queue full).
