Regards,
Since upgrading a cluster to Ganglia v3.1.2, I am getting sporadic XML errors
preventing gmetad from functioning properly. Every time I get a XML_ParseBuffer
error, the WEB page updating stops working and we have to restart gmetad to
get things properly up and running again. There is no consistency regarding the
error, ie the issue seems to trigger an error on different locations and
different points in time. The errors appear even when system load is low. I
have tried to adjust the memory usage parameters in php.ini and extracted XML
data by doing a telnet to the tcp_accept_channel port followed by an xmllint
check. No luck. Here's a snippet of the errors in the /var/log/messages file:

I have also tried to run gmetad in debug mode and redirect the errormessages to
the debug log file, but I only get informative messages and no elaborate
errormessages before and after the point in time when the XML error appear.
All gmonds are running on RHEL4 and are v3.1.2.
Suggestions ?
Relevant server details: RHEL 4 U5 ES, ganglia 3.1.2 , libconfuse v.2.6, apr
v1.3.3.
