Increasing error logging

For some reason, my Cherokee error logs seem to be almost empty. They only
contain the following errors (and I'm not sure what is causing these, but I
can't see any obvious issues resulting from them):
(error) fdpoll-epoll.c:140 - epoll_ctl: ep_fd 16, fd 3: 'Bad file
descriptor' | The issue seems to be related to your system.

If there's an issue starting a server process (eg. FastCGI), I get a "502
Bad gateway" error message, but this does not seem to be logged
anywhere. These errors can be extremely hard to diagnose in a production
environment since there's no debugging information given. I've tried
setting the "Write errors to" setting to both "File" and "System logger",
as well as trying "Standard error" and running Cherokee at the command line.

Any hints on how to increase the level of error logging?

i made the experience that in most cases this is related to some file
access restrictions, e.g. the server has no file permissions to a specific
file. These are sometimes quite hard to debug.

Bad file descriptor is pretty much the only error in my logs too. I wonder
if this is right or maybe too generic.

This is one thing that has stopped me using Cherokee in a production
environment. I don't want to have to worry about errors being "hidden", and
not knowing if/when my sites break for whatever reason. :(
