Apache, Mongrel proxy issue

So I have apache set up as:

<Proxy balancer://mongrel_cluster>   BalancerMember http://127.0.0.1:8000   BalancerMember http://127.0.0.1:8001   BalancerMember http://127.0.0.1:8002   BalancerMember http://127.0.0.1:8003 </Proxy>

Every so often, I get this in the apache error_log and my site hanges:

(70014)End of file found: proxy: error reading status line from remote server 127.0.0.1, referer:..........

OR

(70014)End of file found: proxy: error reading status line from remote server 127.0.0.1

Any ideas?
