The Queue Manager module provides an administrative interface to inspect and
manage Drupal Database Queues.
Why Queue Manager
Sometimes code has bugs. If this code is processing your queues then items can
become stuck and remain unprocessed. The Queue Manager module allows direct
interaction with queue items for inspection and overriding queue processing.
Queue Manager is intended as a debugging/analysis tool, and provides access to
manage Drupal Database queues without having to write the SQL statements
yourself every time.
Queue Manager should be used with caution, as it gives you the ability to delete
queue items which may be being processed. As such, the "admin queue_manager"
permission created by the module should only be granted to roles with advanced
site privileges.
Queue Manager functionality
Queue Manager allows you to:
View all Database Queues in your Drupal database
View the details of individual queue items in a queue
Force the releasing of individual queue items in a queue
Force the deletion of individual queue item in a queue
