SYMPTOMS
A computer that is running Windows NT 4.0 may stop responding (hang) when a process is terminated. When the hang occurs, the user interface will quickly degrade until a reboot is required.



CAUSE
Windows NT 4.0 may hang if a process allows a file handle to be inherited by a child process and the parent process (the original owner of the handle) is shut down unexpectedly. If the child process has initiated a synchronous read on the inherited file handle at the same time that the parent process is terminated, the file handle cannot be destroyed. This causes a deadlock in Object Manager and eventually results in a hang.
