Synopsis
numad bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated numad packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.
Description
The numad packages provide a daemon for NUMA (Non-Uniform Memory Architecture)
systems, which monitors NUMA characteristics and manages placement of processes
and memory to minimize memory latency. The packages also provide an interface
that can be used to query the numad daemon for the best manual placement of an
application.
This update fixes the following bugs:
- Previously, running the numad daemon on a system executing a process with very
large resident memory (such as a Windows Server 2012 guest) could cause memory
swapping. As a consequence, significant latencies under some circumstances
occurred on the system, which could in turn lead to other processes (such as
qemu-kvm) becoming unresponsive. With this update, numad no longer causes memory
swapping in the above scenario, and the consequent latencies and hangs no longer
occur. (BZ#1112280)
- Prior to this update, when a process bound to a set of NUMA nodes depleted the
system memory, the system started memory swapping instead of using other NUMA
nodes for memory allocation. Consequently, the system experienced significant
latencies or became unresponsive. With this update, numad unbinds memory nodes
after moving the process memory, which allows for other nodes to be used for
memory allocation and thus prevents the described latencies and hangs. (BZ#
1112592)
- Previously, the numad daemon ignored existing control groups when localizing
QEMU threads, and as a consequence, it incorrectly consolidated all running
threads into a single control group. This update introduces numad support for
multiple control groups and numad therefore no longer moves QEMU threads into
undesired control groups. (BZ#1112593)
Users of numad are advised to upgrade to these updated packages, which fix these
bugs.
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
