RHBA-2011:1428 - openais bug fix update

Synopsis

openais bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated openais package that fixes three bugs is now available for Red Hat Enterprise Linux 5.

Description

The Application Interface Specification (AIS) is an API and a set of policies for developing applications that maintain services during faults. The OpenAIS Standards Based Cluster Framework is an OSI-certified implementation of the Service Availability Forum AIS. The openais package contains the openais executable, OpenAIS service handlers, default configuration files and an init script.

This update fixes the following bugs:

  • Previously, when OpenAIS was used in a lossy network, and a large number of configuration changes occurred, OpenAIS sometimes terminated unexpectedly. To solve this problem, the underlying source code has been modified, and OpenAIS no longer crashes in the scenario described. (BZ#731460)

  • In rare cases, rapidly starting and stopping the openais service sometimes resulted in a deadlock. This update adapts the underlying source code to prevent such a deadlock, resolving this issue. Deadlock situations no longer happen during a rapid start/stop process. (BZ#739083)

  • Under certain circumstances, the previous version of OpenAIS sometimes used an incorrect sort message queue when the "memb_join" message was sent during recovery. With this update, this error has been fixed, and OpenAIS now uses a correct sort message queue in this scenario. (BZ#739086)

All users of openais are advised to upgrade to this updated package, which fixes these bugs.

Solution

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