Simple proxy config fails occasionally with errors. Apache and nginx are running on 4 web servers. Nginx is used by the web app to proxy between two lucene/solr search servers. Nginx config on each web server: http://pastebin.com/m12448635 Every so often I get a crit error: http://pastebin.com/m4dbfe328 My first expedition into using nginx. Pointing the web app to use one lucene/solr server directly works fine.

I've seen this happending with pf when new connection collide with already existing state in pf for connection in TIME_WAIT state. Solution is to switch firewall off (or at least statefull part of it) for backend connections. Maxim Dounin
