Hello, On Centos 6 with nginx and ispconfig, I'm receiveing this error during the data import from large xml file to drupal website: Code: [error] 11085#0: *16019 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: ..... ( only this 1 error and 502 response during import ) There is a suggestion on serverfault to increase backlog in this case: http://serverfault.com/questions/17...-out-error-with-almost-zero-load-on-a-test-se and here http://wpscale.com/solve-recv-failed-104-connection-reset-by-peer-502-nginx-gateway-php5-fpm/ Please tell what configuration file I should modify to solve this?
