1.130.1. RHBA-2011:0168: psmisc bug fix update
An updated psmisc package that fixes two bugs is now available for Red Hat Enterprise Linux 5.
The psmisc package contains utilities for managing processes on your system: pstree, killall, and fuser. The pstree command displays a tree structure of all of the running processes on your system. The killall command sends a specified signal (SIGTERM if nothing is specified) to processes identified by name. The fuser command identifies the PIDs of processes that are using specified files or file systems.
* Due to an error in memory allocation, an attempt to kill a process group by using the "killall -g" command could fail. With this update, the memory allocation has been corrected, and the killall utility now works as expected. (BZ#668991
* Previously, using the fuser command to list processes that use a UDP port failed to produce the expected results. This was caused by an incorrect use of the /proc/net/tcp socket table instead of /proc/net/udp. With this update, the underlying source code has been adjusted to parse the correct socket table, and fuser no longer fails to list processes for UDP ports. (BZ#669309
All users of psmisc are advised to upgrade to this updated package, which resolves these issues.
