Hi,

It happened again, I attched cib files and log messages of both nodes. The
problem happened last night, but cib file was captured this morning.  As you
can see below log expert, the attrd receives 2 entries for cib_query,
crm_attribute failed to update master score. The fact that the
cib_process_xpath was printed twice and <xpath-query> tag clearly suggests
that the root cause of this problem is xpath_search() returned two entries.
So is it a bug in xml2 library?

Thanks
hj
