RHBA-2012:0461 - Bug Fix Advisory

Topic

An updated procps package that fixes two bugs is now available for Red Hat
Enterprise Linux 6.

Description

The procps package contains a set of system utilities that provide system
information using the /proc file system. The procps package includes the free,
pgrep, pkill, pmap, ps, pwdx, skill, slabtop, snice, sysctl, tload, top, uptime,
vmstat, w, and watch utilities.

This update fixes the following bugs:

• Prior to this update, it was not possible to instruct the "top" utility by

using command-line options to sort processes according to the memory
consumption. This was possible only in interactive mode (by using the "Shift+M"
key combination). This update introduces a new command-line option, "-a", that
instructs the "top" utility to sort processes according to the memory
consumption in batch mode. Note that in Red Hat Enterprise Linux 5, this
functionality is provided by the "-m" option whereas the same option is used for
another feature in Red Hat Enterprise Linux 6. (BZ#746997)

• Previously, the CPULOOP variable effected only the statistical lines

representing the particular CPU cores. With this update, the "top" command
additionally applies the CPULOOP variable on the CPU summary line (that
represents all the CPU cores). (BZ#751475)

• Prior to this update, no development package was generated for procps. With

this update, a separate procps-devel package containing a set of procps
development headers is available. (BZ#766792)

All users of procps are advised to upgrade to this updated package, which fixes
these bugs.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red Hat
Network to apply this update are available at
