ccs_config_validate fails on one node and succeeds on another where both are using the same /etc/cluster/cluster.conf in RHEL 6

Issue

• One node is failing ccs_config_validate and the other is succeeding, where both have the same config. This same config also validates on other hosts as well; its just the one host.
• We have a cluster that was running fine and when we tried to add 2 new services we started getting validation error:

Relax-NG validity error : Extra element rm in interleave
tempfile:24: element rm: Relax-NG validity error : Element cluster failed to validate content
Configuration fails to validate

Then we reverted back to the original configuration and are still getting the same error whenever we try to cman_tool version -r. When i do rg_test test <filename> it doesnt complain, but ccs_config_validate and cman_tool version -r are complaining. The cluster is currently running fine on the original configuration as the new changes weren't validated.
