Back to the top | Give Feedback

This issue occurs because of a race condition between a thread of the Redirected Driver Buffering SubSystem (Rdbss.sys) driver and a thread of the I/O Manager.

When this race condition occurs, an I/O request packet (IRP) is processed by a thread while another thread cancels this IRP. Therefore, the Stop error occurs.
