Stalled Queues and Processing Statuses

Stalls do not occur by design. They are caused by gaps in functionality, user errors, defects, and so forth.

For example, a queue can become stalled when:

  • Multiple domains access the same database and one of the domains is shut down abnormally.

    Items may be stalled in the Started or Working status.

    Note:

    You can use the Domain Status page to correct the problem.

  • A change occurs to the pub/sub runtime tables through direct SQL.

    The copies of the database tables that dispatchers have in memory are not updated. In this situation, you must reboot the dispatchers.
