Updated corosync packages that fix one bug are now available for Red Hat Enterprise Linux 6 Extended Update Support.
The corosync packages provide the Corosync Cluster Engine and C Application Programming Interfaces (APIs) for Red Hat Enterprise Linux cluster software.
Previously, it was not possible to activate or deactivate debug logs at runtime due to memory corruption in the objdb structure. With this update, the debug logging can now be activated or deactivated on runtime, for example with the command "corosync-objctl -w logging.debug=off".
All users of corosync are advised to upgrade to these updated packages, which fix this bug.
