Description

During an OS-Update an agent was not disabled, and it somehow wrote a bad line into the config file:

server:~ # grep syslog_ng /etc/syslog-ng/syslog-ng.conf.2015_10_25_141708
${syslog_ng_conf}
server:~ #

This is very similar to Bug #3107, however, the parenthesis is different, in that Bug a fix was introduced to remove "\$\(syslog_ng_conf\)" via "bundle edit_line edit_syslog_conf_file".

We have had "${syslog_ng_conf}" in our config.

Investigations are still ongoing, how this could happen.

That is rather odd, indeed. I can't see why this would happen from reading the code.

A couple of questions to help us understand:

  • Do you by any chance also have /etc/rsyslog.conf or /etc/syslog.conf files on that machine?
  • Could you find the logs the rudder-agent sent from that around that time that contain "@Log system for reports@"?

I really don't see how this happened, but we can at least add a similar workaround to #3107 and delete that line if it appears too. This way, the problem will be temporary and automatically get fixed rather than hang around...

If you do figure any more out about how this happened, please let us know.
