PROBLEM:  The following problems may be experienced when using tape devices
          with SCO UnixWare 2.1.3:

          1. Reading a file mark does not position the tape after the file
             mark.

          2. Tape commands do not time out even on a controller that supports
             timeouts.

          3. It is possible for the tape driver to get into a state where it
             cannot be opened.

          4. The system panics while reading DAT tapes in variable block mode.

          5. With ptf4042a installed and using dd or cpio, if a tape is 
             opened in non-rewind mode, a block of data is read and the 
             tape is closed, skipping to the EOT side of the next file mark.

          6. When some HBA Drivers, like Mylex or Qlogic, try to allocate
             contiguous 16 - 64MB of memory, a system hang or panic can 
             occur.

PROBLEM:  Some attempts to do block profiling on code containing unexpected
          jump tables in the .text section can fail.

          Also, the package "uccs - UDK Optimizing C Compilation System 
          Feature Supplement" version "(IA32) 7.1.1b" has a later version 
          of the object 'fur'.

PROBLEM:  To improve performance, Tarantella will store Java archives on
          the client browser that is being used.  There are situations
          when these Java archives need to be removed to allow Tarantella to
          install fresh Java archives to alleviate incompatibility issues.

PROBLEM:  Compress(1) output is corrupted when fed through a pipe.  For
          example, the following command-line backup of a file, using
          compress(1) and dd(1M), will complete as usual:

 ls file* | cpio -ocv | compress | dd conv=sync of=/dev/rmt/ctape1 obs=64k

          But, the corresponding tape read (using "cpio -i") will fail with
          errors similar to the following:

 UX:compress:ERROR:uncompress:corrupt input
 UX:cpio:HALT:Unexpected end-of-archive encountered

          The file on tape will be inaccessible.

             MANDPASS When set to YES, this keyword makes passwords mandatory
             for  all logins (overriding PASSREQ).

          I have set MANDPASS=YES in /etc/default/login on my system, but I
          can still log a user with no password into the system.

PROBLEM:  I have a system that is running UnixWare 7 Release 7.1.1. If I run
          what(1) against /bin/cc I get:

             /bin/cc:

                  SCO Modified Binary - update711 - 10/12/99

          and if I run what(1) against /usr/lib/libc.so.1 I get:

             /usr/lib/libc.so.1:

                  SCO Modified Binary - ptf7607e - 11/01/00

          However, if I install the UDK Feature Supplement 7.1.1b onto my
          system, then when I run what(1) against /bin/cc I get:

             /bin/cc:

                  SCO Modified Binary - update710 - 10/30/00

          and with /usr/lib/libc.so.1 I also get:

             /usr/lib/libc.so.1:

                  SCO Modified Binary - update710 - 10/30/00

          Although the modification dates or later, the identification string
          seems to be incorrect in that it is referring to update710.

PROBLEM:  I have a program that prints messages to stderr, which produces a
          beep. However, if the program is running on another tty or virtual
          terminal, the system will still beep. For example, my program
          contains the following (written in C):

             fprintf(stderr, "string");

          Running this program in the background on a virtual terminal,
          or even via telnet, will produce beeps.

PROBLEM:  When more than 9.7GB of disk free space is available, the used

          display of both the CHARM and GUI 'scoadmin' and 'System
          Administration' utilities, respectively.

          The space separating the two fields has been overwritten by the
          large value in the free space field.

          For example, on an 18GB disk drive, the following is displayed

             Filesystem  Mount Point Total(MB) Used(MB) Free(MB) %Used
             /dev/root   /           16865.1   1810.415054.7 11%
