Sudheer Vinukonda commented on TS-2940:
---------------------------------------
This fix unfortunately causes a sort of compatibility issue in 5.3.x. Prior to
the fix, the below default settings would only result in logging the errors to
diags.log (incorrectly, ignoring the "S" part of it).
{code}
CONFIG proxy.config.diags.output.error STRING SL
CONFIG proxy.config.diags.output.fatal STRING SL
CONFIG proxy.config.diags.output.emergency STRING SL
{code}
However, [~sc0ttbeardsley] noticed that, when we updated to 5.3.x with the
default settings, the errors now also get logged into /var/log/messages causing
disk space issues and a potential outage.
> the Fatal() macro always crashes
