Hi, We have been experiencing a weird issue with gmetad.
I am running gmetad v3.4.0 Once in a while now a XML error seems to occur. Like this: /usr/sbin/gmetad[12241]: Process XML (LISA Cluster): XML_ParseBuffer() error at line 525626: Besides what is causing that and why, this causing the Ganglia web front end to hang and become non responsive. After checking the gmetad it seems port 8652 is no longer responding to queries. This does nothing: # telnet localhost 8652 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. /LISA Cluster <after about 1 minute> Connection closed by foreign host. However port 8651 still works: # telnet localhost 8651 | wc -l Connection closed by foreign host. 921410 And when I switch the web frontend from port 8652 back to port 8651 ($conf['ganglia_port'] = 8651;), the web page responds and works again. After restarting gmetad port 8652 also becomes responsive again. It almost seems gmetad has a thread lost it's way or something. Any idea what may be causing this (besides the XML error)? It seems weird to me if 1 port works and the other does not anymore. It might be a bug. I have a dump of the XML (from port 8651 before restarting) available for who might want it, but it is 42 MB.
