RHBA-2013:1503 - kernel bug fix update

Synopsis

kernel bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated kernel packages that fix one bug are now available for Red Hat Enterprise Linux 5 Extended Update Support.

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following bug:

• A bug in the GFS2 code prevented glock work queues from freeing glock-related memory while the glock memory shrinker repeatedly queued a large number of demote requests, for example when performing a simultaneous backup of several live GFS2 volumes with a large file count. As a consequence, the glock work queues became overloaded which resulted in a high CPU usage and the GFS2 file systems being unresponsive for a significant amount of time. A patch has been applied to alleviate this problem by calling the yield() function after scheduling a certain amount of tasks on the glock work queues. The problem can now occur only with extremely high work loads. (BZ#1006164)

All users are advised to upgrade to these updated packages, which fix this bug. The system must be rebooted for this update to take effect.

Solution

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

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258

To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system.
