An updated psmisc package that fixes two bugs is now available for Red Hat Enterprise Linux 6.
The psmisc package contains utilities for managing processes on your system: pstree, killall, fuser and peekfd. 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. The peekfd command attaches to a running process and intercepts all reads and writes to file descriptors.
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.
When parsing a list of command line arguments, the peekfd utility incorrectly used a wrong index. As a result, running the peekfd command with a file descriptor specified caused the utility to terminate unexpectedly with a segmentation fault. This update corrects this error, and the peekfd utility no longer fails to run.
All users of psmisc are advised to upgrade to this updated package, which resolves these issues.
