Hello list,

I have started receiving Proxy Errors from Apache stating that it had  
received invalid data from the server (mongrel). I then checked my  
mongrel  
instances (2) with curl and one of them is not working (it seems to be  
in an  
infinite loop, it just hangs there and doesn’t output anything), the  
other  
instance is working fine… any ideas on what could be happening?

Thanks in advance,

Marcelo.
