Event ID 1004 — Subsystem for UNIX-based Applications Functionality
Applies To: Windows Server 2008 R2
Subsystem for UNIX-based Applications (SUA) Functionality is a measure of how the SUA send-and-receive utility, Psxss.exe, is functioning. When Psxss.exe is operating normally, SUA is able to accept user commands, and port applications over to Windows-based operating systems from UNIX-based operating systems.
|Product:||Windows Subsystem for UNIX-based Applications|
|Message:||PSXSS has encountered a user or group ID with a value that requires careful POSIX offset management. See Knowledge Base article Q306552 for more information. The internal UID is 0x%1%2.|
Check the POSIX offset for the affected domain/user
Unique UID mapping failed, and the current user cannot use Subsystem for UNIX-based Applications until the issue is resolved. An internal error related to PSX offset occurred.
Refer to Knowledge Base article Q306552 at http://go.microsoft.com/fwlink/?LinkId=137164 for more information about the root cause of the error and recovery procedures. If the problem persists, contact Product Support Services for assistance.
Verify that the Subsystem for UNIX-based Applications (SUA) Psxss.exe utility is functioning, first by viewing Psxss.exe in the Windows Task Manager, and then by using an SUA application that you have developed or are porting to Windows to transmit data over the network.
To verify that Psxss.exe is running:
- Open Windows Task Manager by pressing CTRL+ALT+DEL, and then clicking Task Manager.
- On the Processes tab, select the Show processes from all users check box.
- Verify that PSXSS.exe is running.
Next, use an application on which you are working in SUA, or that you are porting to Windows by using SUA, to send some data over the network. For example, attempt to use your application to modify files or documents in another location on the network. If PSXSS.exe is functioning properly, and is active in the list of processes in Task Manager, sending SUA application data over the network should succeed.
