1.108.1. RHBA-2011:1012: openais bug fix update

An updated openais package that fixes various bugs is now available for Red Hat Enterprise Linux 5.
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:
* When there were a lot of nodes left at the same time during the controlled shutdown of the Corosync Cluster Engine, the nodes had to wait for the token timeout for each node. As a result, this unintended behavior slowed down the whole shut down process. The problem has been fixed so that a JOIN message is now sent out with the node removed. (BZ#645299)
* Previously, the amount of open files limit was not handled gracefully. The problem has been fixed in this update so that if the open files limit is now reached, the published server listening socket is withdrawn. Then when a connection is closed, the server listening socket is republished, if necessary. (BZ#611434)
* When the SysV semaphores or Shared Memory (SHM) limit was exceeded, a client could have looped forever. This bug has been fixed and the "SA_AIS_ERR_NO_SPACE" error value is returned if one of the limits is exceeded. (BZ#561546)
* Previously, if the token was lost, the old ring ID information was restored, causing a commit token to be accepted when it should have been rejected. This erroneously accepted commit token led to an assertion, which has been fixed in this update. (BZ#623176)
* When the ring ID file for the processor was less then 8 bytes, totemsrp asserted as a result. This has been fixed so that OpenAIS will now create a fresh ring ID file data when the incorrect number of bytes is read from the ring ID file. (BZ#675206)
All users of openais are advised to upgrade to this updated package, which fixes these bugs.
