Server NGINX
1

Hi!

We just turned on nginx and started directing our customers through it
and
it seems to be working fine. However, I have some questions.

I started monitor the error.log as soon as we started and I get loads of
stuff there. Generally I expect only errors to go to the error log but
this
doesn’t seem to be true for nginx. These are the two messages I get all
the
time

  1. xxx.xxx.xxx.xxx closed keepalive connection (104: connection reset by
    peer).
    As far as I understand from previous mails to this list this is just
    something you’ll get on EVERY request from IE. True?

  2. an upstream response is buffered…
    This too seems to be fine, just that the file is bigger than what can be
    buffered in memory and instead is written to disk before being sent.

This seems to be good stuff so why are the written to the error log?

Thanks!

The “keepalive” messages are logged on info level, while “buffered” are
logged on warn level. Set

 error_log   /path/to/log  error;

to see error, crit, alert, and emerg messages.
