1.180.1. RHBA-2009:0439: bug fix update
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.
All users of psmisc are advised to upgrade to this updated package, which resolves this issue.
