only %d acls inserted, expected %d

Error message

only %d acls inserted, expected %d

What it means

The batch INSERT of ACLs during metadata load reported fewer affected rows than the number of acl records submitted. Indicates a partial insert (database quirk or row-level failure) that would leave the ACL table incomplete, so the transaction is failed rather than committed.

Solutions

1. Retry the metadata load on a clean database
2. Inspect the dump file for duplicate ACL ids that could collapse inserts
