Connection reset by peer and other problems

alcina · July 2, 2013, 1:26pm

Hi guys,

I’m getting a lot of errors on logs right now and we’ve already tried
everything to solve the problem without success.
Everything was running just fine until last week.

We use nginx and php-fpm.
nginx version: nginx/1.2.0

The errors that we getting are from random pages and random domains this
is
not specific.

Here is some errors from the logs:

[error] 26002#0: 8882 readv() failed (104: Connection reset by peer)
while
reading upstream, client: XX.XXX.XX.XXX, server: www.DOMAINX., request:
“GET / HTTP/1.1”, upstream:
“fastcgi://unix:/var/run/php5-fpm/site_live.sock:”, host: “DOMAINX.de”,
referrer:
“Redirect Notice”

This was solved.

The problem was related with New Relic module.
2 weeks to find the problem.
