Debugging another issue

[SplitIce]

Im receiveing lots of messages like  "error] 32211#0: *1650258 upstream sent
no valid HTTP/1.0 header while reading response header from upstream,
client: 178.66.174.159, server: , request: "POST /_serv/chat/read HTTP/1.1",
upstream: "http://212.117.183.43:80/_serv/chat/read", host: "
thewarezscene.org", referrer: "http://thewarezscene.org/chat/""

Its getting on my nerves because I can never reproduce it. This error only
appears on the Nginx(2) node and not Nginx(1) Node. The setup is as follows

Nginx(2)[NL Datacenter] -> Nginx(1)[Offsite] -> Mono[Same location as
Nginx(1)]

Any ideas, a timeout or connection error?
