Updated procps packages that fix several bugs and add one enhancement are now available for Red Hat Enterprise Linux 5.
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.
Due to an inaccurate internal evaluation of the CPU utilization, the "ps --sort" command did not work as expected in some cases. Consequently, some of the values in the final sorted sequence were in an incorrect order. This bug has been fixed and these values are sorted correctly in the described scenario.
Prior to this update, the description of the SWAP field in the top(1) man page could be misleading and confusing. The man page has been fixed by using the SWAP field description from the man page of the successor project procps-ng.
Descriptions for some of the top command switches were missing in the top(1) man page. Switches "-m", "-M", and "-V", which represent sorting by memory usage, memory units detection, and version/help, respectively, have been added to these updated procps packages.
Previously, values shown in the "si" and "so" columns were always zero for the "m" or "M" conversion units. The evaluation has been modified to prevent losses of the arithmetic precision and zero values no longer appears in this situation.
This update introduces a new enhancement in using of the "w" command. Users can switch the value shown in the FROM field to represent IP addresses instead of hostnames. This behavior can be achieved with the "-i" switch.
All users of procps are advised to upgrade to these updated packages that fix these bugs and add this enhancement.
