that error message came from a failed process_xml() function in ./gmetad/process_xml.c line 300 (although the message is in data_thread.c). it would be nice to see the surrounding error messages too to help debug the problem. if there are no error messages around it, then the only "silent" errors that i see would be caused by error'd write_data_to_rrd()'s (i'll make sure that err_msgs get put in there as they should be). here is a quick test to see if there are some corrupted round-robin databases. jump into the rrd directory # cd /var/lib/ganglia/rrds list the size of all round robin databases # find . -ls you should only see two different fixed sizes. if you have some files which are not one size or the other then they are likely corrupted. email the name of corrupted files and then delete them. you don't need to restart gmetad.. it'll notice that the file is missing and make a new database and start filling it in. -matt
