STATUS_OPLOCK_BREAK_IN_PROGRESS
The create path crossed an active oplock break
This informational status belongs to the opportunistic-lock path. It means the open or create operation completed, but it did so while an existing oplock was being broken so another client or handle can observe the file consistently.
For diagnostics, treat this as a cache-coherency and sharing transition. The interesting evidence is the requested oplock level, the breaking handle, the desired access and share mode of the new create, and whether a network redirector or local filter driver is involved.
What to inspect
- Preserve the create options, share access, desired access and oplock level.
- Check whether the client or redirector acknowledged the break promptly.
- Do not treat this as ordinary sharing violation; the operation may already have completed.
