A system deadlock occurs between two threads on an FCB resource for the TXF log in Windows 8.1

Applies to: Windows 8.1Windows 8.1 EnterpriseWindows 8.1 Pro


In Windows 8.1, a deadlock between two threads on a file control block (FCB) resource for the TXF log may occur.

Specifically, assume that one thread is defragmenting the Master File Table (MFT) and has initiated a flush of the TXF log and is waiting for it to complete, while the other thread is flushing the TXF log and is waiting for the FCB. In this situation, a deadlock issue occurs.

When the deadlock occurs, the operating system freezes and requires a hard reset in order to recover.

Cause


This issue occurs because of a bug in the Ntfs.sys driver.
