RHBA-2011:1398 - Bug Fix Advisory

Topic

Updated qpid-cpp packages that fix several bugs are now available for Red Hat
Enterprise Linux 6.

Description

The qpid-cpp packages provide a message broker daemon that receives, stores and
routes messages using the open AMQP messaging protocol along with run-time
libraries for AMQP client applications developed using Qpid C++. Clients
exchange messages with an AMQP message broker using the AMQP protocol.

This update fixes the following bugs:

• Due to a regression, a memory leak was introduced that prevented the broker

from correctly releasing messages. Consequently, the broker's memory footprint
grew indefinitely. A patch has been provided to address this issue, and the
memory leak no longer occurs in the described scenario. (BZ#728586)

• After the upgrade of MRG Messaging from version 1.2 to version 1.3, the qpidd

daemon terminated unexpectedly on some of the cluster nodes. With this update,
the broker code has been fixed to handle all cases when a faulty client sends
frames before completely opening the connection, thus fixing this bug.
(BZ#734608)

• Previously, specifying an invalid IP address for a destination broker caused a

repeatable file descriptor leak. A patch has been provided to address this
issue, and the file descriptor leak no longer occurs in the described scenario.
(BZ#732063)

• Prior to this update, when a large message (over 4KB) was sent from the

python-qpid client to the broker, the connection became unresponsive and other
clients were unable to connect to the broker. This bug has been fixed, and
clients no longer hang in the described scenario. (BZ#733543)

• Under heavy load, the broker generated a large number of timer late/overrun

warning messages. Though the messages themselves were usually inoffensive, the
time to log them individually caused long (up to several seconds) delays and
inflated log files. With this update, logging output for these messages has been
restricted to the "--log-enabled=info" option, thus preventing this bug.
(BZ#690107)

All users of qpid-cpp are advised to upgrade to these updated packages, which
fix these bugs.
