5.252. procps

Updated procps packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
The procps packages provide a set of system utilities to 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.

Bug Fixes

BZ#851664
Prior to this update, the 'si' and 'so' values were always zero for "m" or "M" units. This was caused by an arithmetic precision loss in the expressions used for the calculations. This update modifies the expressions to avoid precision losses.
BZ#875077
Prior to this update, the vmstat tool could be terminated unexpectedly raising the SIGFPE exception when the total sum of 'us', 'sy', 'id', 'wa' and 'st' values returned by the kernel was zero. This situation could only appear on certain specific platforms. this update modifies the internal evaluation so that the vmstat tool is more robust and does no longer terminate.
All users of procps are advised to upgrade to these updated packages, which fix these bugs.

Bug Fixes

BZ#746997
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#751475
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#766792
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.
All users of procps are advised to upgrade to this updated package, which fixes these bugs.
