sysstat bug fix and enhancement update

An updated sysstat package that provides several bug fixes and adds an
enhancement is now available.

The sysstat package provides the sar and iostat commands. These commands
enable system monitoring of disk, network, and other I/O activity.

This updated sysstat package provide fixes for the following bugs:

* the data for TTY device activity reports was not generating correctly.
Consequently, the command "sar -y" failed, returning the error: "Requested
activities not available in file". In this updated package, sar has been
corrected so the -y option outputs the TTY device activity.

* on the Itanium(R) architecture, when running the "sar -I" command with
appropriate values to report statistics for a given interrupt, the output
was incorrect due to a change in the kernel. In these updated packages, an
error message is displayed instead of incorrect output, thus resolving this
issue.

* the command "iostat -n" was not closing the file handles it opened. This
may have caused iostat to crash, returning the message: "fopen: Too many
open files". In this updated package, iostat now closes all the file
handles it creates, which resolves this issue.

In addition, the updated sysstat package provides the following enhancement:

* the iostat "-n" option now displays extended output for NFS: a "rops/s"
column that displays read operations per second, and a "wops/s" column that
displays write operations per second.

Users are advised to upgrade to this updated sysstat package, which
resolves these issues and adds this enhancement.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
