  • Closed as program error.

Error description

  • Not able to pull in messages from WebSphere MQ when using
    WebSphere MQ adapter and when the messages contain
    non-XML and non-printable characters. Adapter doesn't
    bootstrap associated workflows and gets into a loop.
    
    Test data has corrupted 'Return-to Queue Name' and 'Return-to
    Queue Manager' in the MQ header.
    
    This issue has caused rapid error message growth in the logs on
    customer's server that eventually crashed the system. For
    example, in 15 seconds, 20 MB of log is generated of the same
    set of errors repeatedly.
