Research direction

The issue names an object manager but provides no source file, test, reproduction steps, or version output. Start by locating the object manager and its lock usage, then identify a reproducible incorrect-lock scenario and the relevant existing tests. Done means the locking behavior is corrected and the regression is covered by a test.
