hi, all  
after i switched from nginx + thin to nginx + passenger, the error  
“MemCache::MemCacheError: No connection to server” always shows up in  
the log. i did what the post  
“[Phusion Passenger and memcache-client revisited – info.michael-simons.eu](http://info.michael-simons.eu/2009/03/23/phusion-passenger-and-memcache-client-revisited/)”  
said in my enviroment.rb, but i still get the same error.

any ideas? thanks a lot
