Hi, I''m trying to run ror server on background (i.e. the daemon server) I ran the following cmd: rails server -e production -d In the beginning, everything is OK. I can go to the first page (index page). However, when I try to query something (I build a small search engine), it does not responding. The ruby is running, but the whole app does not responding. However, the interesting thing is when I try these cmd: rails server or rails server -e production or nohup rails server -e production & All thing went smoothly! I tried to find out what is the problem, I have two link in the index page that use a some controller (without a model). They response well. When I tried query (with a model), it went dead, and never come back again, here is the last log I can see: Started GET "/recommend?utf8=%E2%9C%93&abstract=pagerank&commit=Get+Recommendations" for ***.***.***.*** at 2012-06-11 23:03:26 -0400 Processing by RecommendationController#recommend as HTML Parameters: {"utf8"=>"รข", "abstract"=>"pagerank", "commit"=>"Get Recommendations"} Also I can not go back the index page again! This is really a strange problem, can anyone help me solve this problem?
