2593825 - MPL Attachment is not writing because Circuit Breaker is open

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

1. MPL attachments/logs are not saved/displayed in CPI

OR

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 / tail log, there are entries like:

Could not save MPL Attachment "<attachment name>" created by Integration Flow "<Integration Flow Name>" because circuit breaker is open

or

MPLAttachmentCircuitBreaker-1#...#Count of xxxxxxxxx bytes for last 86400000 ms exceeds threshold 1073741824|
