I don't have your original post, so you may have outlined these details, but: Are you running more than 1 mongrel? What are you using to balance: Apache's mod_proxy, hardware load balancer, or something else (nginx, etc)? Last time I checked, Nginx and Apache use round-robin for rotating through your mongrel ports. So, if one mongrel process is taking awhile to respond, the balancer can't tell and could send a new user to that port causing a hanging request. There are alternatives that will allow the hung/slow ports to be skipped after a certain threshold, but nothing that uses apache (to my knowledge). Here's a recent one for Nginx: http://brainspl.at/articles/2007/11/09/a-fair-proxy-balancer-for-nginx-and-mongrel If you're just using one mongrel, then this won't apply. What Kirk is explaining is that it's not mongrel that is hanging on the request, it's the (single-threaded) Rails code. He should know all about that seeing as he wrote Swiftiply (which you might look into as a solution). http://swiftiply.swiftcore.org/ ed > > I can't even get a page not found 404 error if I feed it a bad address, > the mongrel server is locked up and not responding, to anybody. > > Maybe I don't understand the linkage between my web app and the web > server, I didn't think my application by running a periodic update could > cause the server to refuse any new connections?
