This article describes a hotfix that is available for users of the following component:

• Utilities and SDK for Subsystem for UNIX-based Applications (SUA)

This hotfix incorporates daylight saving time (DST) changes in Pakistan and in Morocco in 2008.

You have a Subsystem for UNIX-based Applications (SUA) application that prints log messages from the system logger daemon (syslogd) on Windows Server 2003 R2-based, Windows Vista-based, or Windows Server 2008-based computers. When you run this SUA application, ISO 8859 characters are printed incorrectly. For example, the string “Ümläütén” is printed as the following string:

\M-\ml\M-d\M-|t\M-in

However, if you print the string from applications such as WordPad or Notepad, the string is printed correctly.

This article describes a hotfix that is available for users of the following components:

• Windows Service for UNIX
• Utilities and SDK for Subsystem for UNIX-based Applications (SUA)

This hotfix incorporates daylight saving time (DST) changes in Argentina, in Chile, in Egypt, in Iran, in Iraq, and in Israel.

On a computer that is running Subsystem for UNIX-based Applications (SUA) in Windows Vista, you cannot perform certain privileged operations such as creating sockets, opening disk devices, opening driver device objects, and opening section objects. This is the case even if you are a member of the domain administrators group or a member of the local administrators group.

Only the built-in domain administrator or the built-in local administrator can perform these privileged operations.

Consider the following scenario. On a Windows Vista-based computer, a Subsystem for UNIX-based Applications (SUA) process forks a child process. Because the SUA process is not required to wait for the child process to be completed, the SUA process sets the value of the SIGCHILD signal to SIG_IGN. In this scenario, the SUA process expects the child process to be cleared when the child process is complete. However, the child process is unexpectedly marked as a zombie process instead.

Subsystem for Unix-based Applications: A source-compatibility subsystem for compiling and running custom UNIX-based applications on a computer running a Windows server-class operating system.

When you try to run a Subsystem for UNIX-based Applications (SUA) application on a Windows Vista-based computer, the application may stop responding.
