Koushik Biswas commented on TS-2490:
------------------------------------
Guys what about adding a setting like "config.watch_sleep_time" to ATS? I agree
that will not fix the problem described in TS-2058, as it will need to be in
minutes, and that is impractical. However, while you decide on the best and
most elegant fix to this start-up problem, "config.watch_sleep_time" would
unblock people who just need traffic_cop to wait 10 - 20 seconds more before
pulling the trigger. It is a 10 minute patch that will help someone out there.
Please let me know your thoughts.
> 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.
