On Centos 6 with nginx and ispconfig, I'm receiveing this error during the data import from large xml file to drupal website:
[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:
Please tell what configuration file I should modify to solve this?
