Description Ralph Böhme 2026-09-02 09:58:30 UTC 
delay_for_handle_lease_break_send() blocks an SMB2 CLOSE when the handle had INITIAL_DELETE_ON_CLOSE set, when the target file has a H-lease by a different open.

The server waits up to OPLOCK_BREAK_TIMEOUT (35s) for that other client to ACK the lease break. If the ACK doesn't arrive in time, the code remaps NT_STATUS_IO_TIMEOUT to NT_STATUS_ACCESS_DENIED and fails the close.

The problem is that we set a timeout on the req from delay_for_handle_lease_break_send() which has the same timeout, but is setup shorty before, the actualy lease-break timeout setup in fsp_lease_update().

Have patch, need bugnumber.
