3353209 - 'Circuit breaker is open' error in Cloud Integration when using Standard Packages/iFlows


In Cloud Integration, you have Standard Integration iFlows that will write Message Processing Log (MPL) attachments.
It is noticed that MPL Attachments are intermittently not written/found in Message Monitor, although the message processing is successful, and you are certain the step to write MPL Attachment is successfully executed. But as you are using Standard iFlows (of standard package) you cannot modify any iFlow to avoid the 'circuit breaker is open' issue. In the LJS trace, there are entries like one of below:

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