Dear SCO Customer, 
 
Support Level Supplement (SLS) ptf7631e, the UnixWare 7.1.1 libsocket  
Supplement, addresses the following problems: 

SLS ptf7631c addresses this issue:

        Libsocket maintains a pointer to libresolv code; the pointer may 
        become stale causing a core dump of Apache when used with PHP. 

SLS ptf7631e addresses this issue:

        Interrupted libsocket accept() calls previously caused an ERESTART
        error instead of restarting the system call.  This can cause
        applications to fail.  For example, when run with native threads,
        the Java VM may issue a ServerSocket socketAccept exception.
