What appears to be happening is that somehow the real servers are not always able to send data back to the client that made the request. When I view apache's status page (/server-status/) I'll see many connections in the "W" (Sending Reply) state, and they'll stay there until they either time out or I restart apache.

Here a few suggestions:

* Is the loadbalancer able to fetch pages from the reals? Check this 
with lynx.
* Have you checked that the default route on all reals points to the 
loadbalancer? If you use iproute with source routing double check your 
routing table with "ip rule"
* Try turning the apache configuration option keepalive to OFF.
