Leif Hedstrom commented on TS-2490:
-----------------------------------
What if we don't allow traffic_cop to kill anything until it has reached a
"good" state? So, something like
fail (no restart)
fail (no restart)
fail (no restart)
success
success
...
fail (no restart)
fail (restart)
(remember, it takes two failures in a row to restart). This also avoids an
annoying step where ATS goes into a loop of constant restarts because it can't
startup properly.
> traffic_cop kills TS process before it completes starting

> Key: TS-2490
> URL: https://issues.apache.org/jira/browse/TS-2490
> Project: Traffic Server
> Issue Type: Bug
> Components: Cop, Core
> Reporter: David Carlin
>
> Several things can slow traffic_server startup
> - Long remap.config file
> - Long list of certs in ssl_multicert.config (see TS-2058)
> - Plugins that take too long to initialize
> You end up with a race condition where traffic_server never starts because
> traffic_cop kills it before it completes.
> There was a hack at Yahoo to address this - a YTS setting
> proxy.config.watch_sleep_time to change the heartbeat interval as a
> workaround. Doesn't seem like a practical solution for issues like TS-2058
> where the heartbeat would need to be in minutes.
