> 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.

> 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.
