[collectd] Collectd 5.8.1 complains about config errors without giving details

[Mitch Patenaude]

I’m running collectd-5.8.1-5.el7.x86_64 on CentOS 7.7.  I have a problem on two machines where collectd complains on startup about config errors:

[root at xapp04-lv mpatenaude]# collectd
plugin_load: plugin "cpu" successfully loaded.
plugin_load: plugin "interface" successfully loaded.
plugin_load: plugin "load" successfully loaded.
plugin_load: plugin "memory" successfully loaded.
Error: Reading the config file failed!
Read the logs for details.

However, there aren't any errors in the logs:

I've tried commenting out various parts of the config file without success.

Any idea what could be going wrong?  I have been looking for a way to increase the verbosity of the logging, but haven't found it.

Thanks,
