在通过tmux输出缓冲区搜索时，Rails会冻结

I'm running Rails 3.2.6 in development mode using tmux. When I scroll through the output buffer of the Rails server (run using rails s) using tmux, the server freezes and doesn't process any requests. When I escape scrollback mode, the server starts working properly again.I'm running Rails 3.2.6 in development mode usi
