clustermon bug-fix update

Type/Severity

Bug Fix Advisory

Topic

Updated clustermon packages that fix several bugs are now available for Red Hat
Enterprise Linux 5.

Description

The clustermon packages are used for remote cluster management. The modclusterd
service provides an abstraction of cluster status used by conga and by the
Simple Network Management (SNMP) and Common Information Model (CIM) modules of
clustermon.

This update fixes the following bugs:

• Prior to this update, under certain circumstances, outgoing queues in
  inter-node communication of the modclusterd service could grow over time. To
  prevent this behavior, the inter-node communication is now better balanced and
  queues are restricted in size. Forced queue interventions are logged in the
  /var/log/clumond.log file. (BZ#618321)
  
• Prior to this update, execution of external programs (such as
  /usr/sbin/clustat) from within the modclusterd daemon or ricci's helper program,
  modcluster, could make these unresponsive. In such a case, processes depending
  on the programs could also become unresponsive or indicate an error. For
  example, in tools like luci, the affected node could be listed as having
  communications problems, or the cluster creation could become unresponsive.
  Patches have been applied to address this issue, and deadlocks no longer occur
  when executing external programs. (BZ#736814)
  

All users of clustermon are advised to upgrade to these updated packages, which
fix these bugs.

Solution

relevant to your system have been applied.
