RHBA-2015:1441 - numad bug fix update

Synopsis

numad bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated numad packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The numad packages provide a daemon for Non-Uniform Memory Architecture (NUMA) systems, 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.

  • Previously, the numad daemon could run out of file descriptors. When upgrading numad on KVM-Hypervisor, the following error messages were returned, after which numad terminated unexpectedly:

    Could not write 1 to /cgroup/cpuset/libvirt/qemu/vm_name/emulator/cpuset.mems -- errno: 13

The underlying source code has been fixed, and numad no longer crashes in this situation. (BZ#1150585)

  • Prior to this update, superfluous quotes in the numad initscript confused the daemon() function, which subsequently constructed a wrong argument. As a consequence, the following error message was returned:

    Starting numad: /usr/bin/dirname: extra operand -i' Try /usr/bin/dirname --help' for more information.

A patch removing the quotes around daemon() parameters fixes this bug, and the error messages are no longer returned. (BZ#1186724)

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.
