------------------------------------------------------------

I am working on this now.  I think the upper limit on restart time seems reasonable but was wondering if I could get some clarification re: exponential backoff and # of restarts.  I think it definitely makes sense to have it do exponential backoff up to some upper limit but once we reach that limit do we wish to continue attempting to restart or after we get to the point where we've waited 60 seconds for a restart do we want that to be our last attempt?

It looks like David's initial concern wouldn't be solved unless we have a limit on the # of times we restart in addition to doing exponential backoff for time between restarts.  What do we think would be a reasonable # of attempts?

> If there is a problem with the config and traffic_server doesn't start, traffic_manager still tries indefinitely to restart ATS.  This fills up the TS logs, /var/log/messages, and can send out hundreds of emails via proxy.config.alarm_email.
> Is it possible to have traffic_manager only attempt X number of restarts?  Or X number of restarts in a given period of time?
