Alan M. Carroll commented on TS-3312:
-------------------------------------
Yes. I think my recommendation is to not pass the time out via releaseSession()
but instead have another method which explicitly sets the timeouts and call
that from the HttpSM cleanup logic. This will cover anything put in the pool
*and* sticky sessions without convoluted logic. The keepalive value would be
easily accessible and overridable. I'd keep the timeout resetting
::releaseSession as they are now so you get a timer reset then but tweak the
time out value through a specific method.

> Project: Traffic Server
> Issue Type: Bug
> Components: Core, HTTP
> Reporter: Leif Hedstrom

> Attachments: keep_alive3.diff

> Doing some basic testing, with the following settings:
> {code}
> CONFIG proxy.config.http.keep_alive_no_activity_timeout_out INT 120
> CONFIG proxy.config.http.transaction_no_activity_timeout_out INT 30
> {code}
> I see ATS timing out the origin sessions after 30sec, with a
> {code}
> CONFIG proxy.config.http.transaction_no_activity_timeout_out INT 30
> {code}
> What's also interesting, after I made a config change per Geffon's suggestion:
> {code}
> CONFIG proxy.config.http.origin_min_keep_alive_connections INT 10
> {code}
> I see the following in the diagnostic trace:
> {code}

> [session_pool] session 0x1cc5aa0 received io notice [VC_EVENT_EOS]
> {code}
> So, not only is it resetting the timeout twice, it also gets a VC_EVENT_EOS.
> I first though it was the origin that closed the connection, but from what I
> could tell, the timeout on the origin was set to 60s.
