Dear SCO Customer,

The enclosed Support Level Supplement (SLS) PTF3150, the New kma Driver 
for Statistics Reporting Supplement, installs an updated kma driver
that corrects the following problems:

1. Incorrect statistics are reported, resulting in sar and rtpm
reporting erroneous numbers for kernel memory usage.

2. kma pools are only shrunk every 30 seconds by default.  Under heavy
load, this can cause the kma buffers to be depleted, resulting in poor
system performance.

----------------------------------

PTF3150 should only be installed on these releases:

   SCO UnixWare Application Server Release 2.1.1, 2.1.2
   SCO UnixWare Personal Edition Release 2.1.1, 2.1.2


Installation Instructions
-------------------------

1. Download the ptf3150.Z and ptf3150.txt files to the /tmp directory
   on your machine.

2. As root, uncompress the file and add the package to your
   system using these commands:
