I think it is even simpler than that. You have "maxconn 300" on your servers, and you don't have "option httpclose", which means that clients can maintain a keep-alive connection open an unused after they retrieve an object. By reducing "timeout client", you are forcing those connections to die faster, but it's still not the right way to do this. Please simply add "option httpclose" and I'm sure the problem will definitely vanish.
