How can `blf` be `NULL` since you just allocated it? And in that case the
condition should be `NULL == blf || NULL == blf->m_fp` because if `blf` is NULL
you're failed as well.

> 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.

> 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.
