This happens daily and I cannot say that it happens during the scheduled refresh because the time of these errors varies(may be because of queuing). But the interface on these errors has a value “Identity Refresh”
We had the same issue and here is how we got it fixed:
SailPoint determined it was caused by multiple aggregation jobs running concurrently, triggering accidental refresh, and causing account creation request. The issue was resolved by enabling a feature flag that prevents duplicate account creation.
