Event ID 1016 — Subsystem for UNIX-based Applications Functionality

Updated: December 16, 2008

Applies To: Windows Server 2008 R2

yellow

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.

Event Details

Product: Windows Subsystem for UNIX-based Applications
ID: 1016
Source: Microsoft-Windows-SUA-Psxss
Version: 6.0
Symbolic Name: PSX_EXCEPTION
Message: Unexpected Exception pid=%1 cid=%2.%3 code=%4 fc=%5

Resolve

Add signal handler for SIGEXCEPTsignal in POSIX application

If an exception occurs in a POSIX application, the exact nature of the exception is detailed in the event log.

If an application on which you are working in Subsystem for UNIX-based Applications has generated this error, add a signal handler to your application to handle the SIGEXCEPT signal.

Detailed information about working with signals and adding a signal handler to applications is available in the Help included with the Utilities and Software Development Kit (SDK) for Subsystem for UNIX-based Applications download package, available from the Microsoft Web site (http://go.microsoft.com/fwlink/?linkid=67558). Specifically, you can find information about signal handling in Help for Porting Applications to Subsystem for UNIX-based Applications (PortApps.chm).

Verify

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:

  1. Open Windows Task Manager by pressing CTRL+ALT+DEL, and then clicking Task Manager.
  2. On the Processes tab, select the Show processes from all users check box.
  3. 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.
