RHBA-2013:1338 - Bug Fix Advisory

Topic

Updated procps packages that fix two bugs are now available for Red Hat
Enterprise Linux 5.

Description

The procps packages contain a set of system utilities that provide system
information. The procps packages include the following utilities: ps, free,
skill, pkill, pgrep, snice, tload, top, uptime, vmstat, w, watch, and pwdx.

This update fixes the following bugs:

• In some cases, for example, with VMware ESX guests and C-states/CPU switched

off, the sum of idle and non-idle ticks returned by the kernel might have been
zero. Consequently, this could have caused arithmetic exceptions. With this
update, the zero sum is evaluated as if there were idle cycles, and the
arithmetic exceptions no longer appear. (BZ#785169)

• Previously, there was a misleading description of the SWAP field in the "top"

tool. The Red Hat Enterprise Linux version 5 kernel does not export the VmSwap
field in the /proc/#PID/status file, and therefore it was not possible to get
the size of the swapped out portion of the task's address space. In the case of
Red Hat Enterprise Linux 5, the SWAP field displayed by the "top" tool
represented the non-resident portion of the task's address space instead. With
this update, the SWAP description has been changed from "Swapped size" to
"Non-resident size." (BZ#869140)

Users of procps are advised to upgrade to these updated packages, which fix
these bugs.
