Nginx as Load Balancer Connection Issues

[ggrensteiner]

Have you tried using HTTP 1.1 keepalive connections from nginx to
apache?  They became available in 1.1.4 and will re-use sockets rather
then close them and leaving them in TIME_WAIT

Be sure to remember to turn on keepalive in your apache config as well.
