If you declare one as a member, it will have the same life time as the

> Project: Traffic Server
> Issue Type: Improvement
> Components: Logging
> Reporter: Miles Libbey
> Assignee: Daniel Xu
> Labels: newbie
> Fix For: 6.1.0

>
> (from yahoo bug 913896)
> Original description
> by Leif Hedstrom 3 years ago at 2006-12-04 12:42
> There might be reasons why this file might get filled up, e.g. libraries used
> by plugins producing output on STDOUT/STDERR. A few suggestions have been
> made, to somehow rotate traffic.out. One possible solution (suggested by
> Ryan) is to use cronolog (http://cronolog.org/), which seems like a fine idea.

> Maybe consider rolling diags.log as well. -Feature enhancement.
>
> Comment 2
> by Kevin Dalley 13 months ago at 2009-03-04 15:32:18
> When traffic.out gets filled up, error.log stops filing up, even though
> rotation is turned on. This is
> counter-intuitive. Rotation does not control traffic.out, but a large
> traffic.out will stop error.log from being
> written.
