Hi Torsten, just jumping in here and hooking into the above.
How does it work with Apache children/threads that may be acting as a
VirtualHost's having their own ErrorLog ?
My experience is that anything logged by mod_perl modules running "in" a
VirtualHost using explicit warn() or $r->log_error() or $r->log->info()
etc.. ends up in the VirtualHost's ErrorLog, but some run-time messages like
"Use of uninitialized value in concatenation (.) or string at .." end up
in the "main" Apache error log. How does that come about ?
