RHBA-2009:0439 - Bug Fix Advisory

Topic

An updated psmisc package that fixes a bug is now available.

Description

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.

This updated psmisc package fixes the following bug:

• calling the command "fuser -m <device>" failed to detect open files on a

file system that had been lazily unmounted (by calling "umount -l
<device>", for example). The fuser utility detects open files on
lazily-unmounted file systems with this updated package.

All users of psmisc are advised to upgrade to this updated package, which
resolves this issue.

Solution

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
