Fixed In Version: cluster-3.0.12-23.el6_0.7
Doc Type: Bug Fix
Doc Text:
Due to an incorrect call of a function from the libxml2 library, each update of cluster configuration caused the configuration library to leak a small amount of memory. This update applies a patch that removes this incorrect function call, and updating cluster configuration no longer leads to memory leaks.

Verified with
cman-3.0.12-23.el6_0.7.x86_64

2 node cluster, start up cluster (no ricci), increase version on one node and
restart it, 2nd one begins the loop. Without the patch the memory footprint
(RSS) increases by about 1M per minute. With the patch there was no increase
for about 20 minutes of looping.
