2593825 - MPL Attachment is not writing because Circuit Breaker is open in Cloud Integration

Symptom

In Cloud Integration (former CPI), you have integration flows that will write Message Processing Log (MPL)  attachments. It is noted intermittently, that:

  1. MPL attachments are not saved/displayed in Cloud Integration Message Monitor;
  2. Not all MPL attachments are being written as design.

While message processing itself is not being affected due to this. For symptom 2, in the LJS trace, there are entries like one of below:

  1. Could not save MPL Attachment "<attachment name>" created by Integration Flow "<Integration Flow Name>" because circuit breaker is open
  2. MPLAttachmentCircuitBreaker-1#...#Count of xxxxxxxxx bytes for last 86400000 ms exceeds threshold 1073741824|
