Updated libqb packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The libqb packages provide a library with the primary purpose of providing high performance client server reusable features, such as high performance logging, tracing, inter-process communication, and polling.
The libqb packages have been upgraded to upstream version 0.17.1, which provides a number of bug fixes and enhancements over the previous version. One of the notable changes gives components consuming inter-process communication (IPC) API of libqb more control over IPC buffer sizes. The ability to utilize larger buffer sizes in a consistent way between the IPC client and server allows pacemaker to scale much further in the number of resources the cluster can manage. (BZ#1110042
