RHBA-2015:0963 - Bug Fix Advisory

Topic

Updated libqb packages that fix one bug are now available for Red Hat Enterprise
Linux 7.

Description

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.

This update fixes the following bug:

• Previously, processes using the libqb library's main event loop API for

interprocess communication (IPC) terminated unexpectedly with an assert error
when more than 64 thousand IPC connections had been created and terminated. Now,
the assert error has been fixed and libqb properly reclaims memory after IPC
connections are terminated. (BZ#1212297)

Users of libqb are advised to upgrade to these updated packages, which fix this
bug.

Solution

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