I want to send all error output to a process for specialized logging.
I know that you can use CustomLog with a pipe. However, will that
capture output from things like 'print STDERR ...' or if an XS module
directly writes to stderr? I need that output to also go to my logging
process.
Does anyone

One operational issue with this is that if the logger process dies,
existing httpd processes will get a SIGPIPE signal on subsequent
writes. Restarting the logger process does not restore the lost
connections.

My concern is about what happens in this scenario:

On Linux the ErrorLog of the base server is always opened on file
descriptor 2 that means stderr. So, a reader that reads this stream
gets everything (under normal conditions) that Apache, Perl or any XS
module writes to stderr.
Hi Torsten, just jumping in her
