Rhba-2009:1104: Bug-Fix Update; Rhba-2009:0417: Bug Fix Update - Red Hat ENTERPRISE LINUX 5.4 - TECHNICAL NOTES Manual

Chapter 1. Package Updates
The openais packages provide the core infrastructure used by Red Hat Cluster Suite and GFS.
This update fixes the following bug:
• When a node is sending heavy transmissions, and it is killed and restarted, it can sometimes lead
to complete cluster failure by not allowing new communication to occur from that node. This is a
regression in the z stream.

1.160.2. RHBA-2009:1104: bug-fix update

Note
This update has already been released (prior to the GA of this release) as errata
RHBA-2009:1104
Updated openais packages that fix various bugs are now available.
The openais packages provide the core infrastructure used by Red Hat Cluster Suite and GFS.
This update fixes the following bugs:
• The CFG library, which is used to enable redundant ring, does not function properly.
• The CPG service, which is used throughout the cluster software, can sometimes segfault under
certain loads.
• On ppc architectures, the IPC system can segfault because of how va_args and unions operate on
these platforms.
• The totempg subsystem in openais can sometimes throw away a message, which can result in
cluster failure.
• The IPC system contains a problem with the CPG service. The problem causes the wrong error
code to be returned when the library user has insufficient permissions (regression).
• A race condition can cause the CPG service to have unexpected behavior (regression).
• Configuration changes in the CPG service could be delivered out of order (regression).
Users should upgrade to these updated packages, which resolve these issues.
