So I launched my sinatra app like this and from my google searches the -J arg looks like what I want. jruby -J-Xmx1024m -S recordset.rb When I tried to download the csv file (which the server puts into the zip file and then crashes), I got the same heap space error, but it seemed like it did run longer before it crashed. II try to increase that number much higher than 1024m, I get: Error occurred during initialization of VM Could not reserve enough space for object heap JVM creation failed -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
