> Key: TS-3364
> URL: https://issues.apache.org/jira/browse/TS-3364
> Project: Traffic Server
> Issue Type: Improvement
> Components: Configuration
> Affects Versions: 5.3.0
> Reporter: Sudheer Vinukonda
> Fix For: sometime
>
>
> Currently, traffic_server fails to initialize when it encounters fatal errors
> in loading the config files during start up. During dynamic reloading of
> config files (e.g. via traffic_line), traffic_server rejects new config and
> falls back to existing/old config (however, if there was a traffic_server
> crash/restart subsequently, that can again result into failing to initialize).
> This jira proposes to make the behavior of traffic_server when it encounters
> such fatal errors configurable via a new setting
> {{proxy.config.ignore_fatal_errors}} with the below options:
> {code}
> 0 : All errors are fatal, do not load/reload
> 1 : Ignore a bad config line, continue with the rest
> 2 : Ignore a bad config line, stop parsing the file further
> ..
> {code}
