RHBA-2009:0086 - Bug Fix Advisory

Topic

Updated clustermon packages that fix various bugs are now available.

Description

The clustermon packages are used for remote cluster management.

This package addresses the following bugs:

• When installing the cluster-snmp package and its dependencies,

installation of dlopen would fail because of an undefined symbol. This has
been corrected by setting LDFLAGS to += ../common/*.o -lcman in the
snmp-agent Makefile. dlopen now installs correctly with the cluster-snmp
package.

• Using the SNMPD plugin to retrieve cluster information on a blocked

socket would cause SNMPD to hang as it waited for additional data to arrive
on the socket. SNMPD no longer hangs when retrieving cluster information
from a blocked socket by setting sock.nonblocking(true) in the
get_cluster() method of the ClusterMonitor.

All clustermon users are advised to upgrade to these updated packages,
which resolve these issues.
