Hi, I’m currently running a very simple rails (2.3.8) app using ironruby 1.0. At the moment I’m only running the app in development mode using Webrick but I have some concerns about the amount of memory being used by ir.exe. Each web page refresh consumes an additional 5 Mb of memory which seems to be never released (the actually number seems to increase with the amount of info being retrieved/displayed). Eventually my PC (XP 32-bit) runs out of memeory and WeBrick needs to be restarted. I’d like to know whether this is normal and whether this will continue if I move to IIS rather than WeBrick. Or could this be a result of my incompotence in configuring and coding my app! Any other insights would be gratefully appreciated. Thanks. ---

Hi James, can you try (not during development, just for a test) do the same test but run webrick with a production RAILS\_ENV ? For Rails 2.3.8 this should be: script/server -e production Most of the time (most, not all 🙂 this is related to the development auto-reloading feature. hth, – Thibaut ---

Thibaut, Thanks for the reply. I was wondering whether that was the case. I’ve tried starting in production but get the following error… C:/ruby\_iron/lib/ironruby/gems/1.8/gems/activesupport-2.3.8/lib/active\_support/dependencies.rb:154:in `require': no such file to load -- activesp (MissingSourceFile) from C:/ruby_iron/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:30:in`require’ from C:/ruby\_iron/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:30:in `require' from C:/ruby_iron/lib/ironruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:154:in`require’ from C:/ruby\_iron/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:30:in `require' from C:/ruby_iron/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:30:in`require’ from C:/ruby\_iron/lib/ironruby/gems/1.8/gems/activesupport-2.3.8/lib/active\_support/dependencies.rb:156:in `require' from C:/ruby_iron/lib/ironruby/gems/1.8/gems/activesupport-2.3.8/lib/active_support/dependencies.rb:490:in`new\_constants\_in’ from C:/ruby\_iron/lib/ironruby/gems/1.8/gems/activesupport-2.3.8/lib/active\_support/dependencies.rb:154:in `require’ Any ideas?

Well you I’d guess you’re trying to use the activesp gem ( [http://www.xaop.com/labs/activesp](http://www.xaop.com/labs/activesp)) ? If so it’s apparently not available; not sure if it’s related to ironruby or not at this point (it could, but maybe not). – Thibaut ---

Duh! Thanks Thibaut I was reading activesp as active\_support. Having one of those days. I’d left a reference to activesp in from a previous attempt to integrate with Sharepoint (not very succesfully - hence the move to ironruby) I’ve now got ironruby running in production and my initial tests show that whilst the memory usage does increase with usage, it does seem to top out, and then stop increasing (and even descreases) and is no longer impacting the performance as it was when running in development mode. Thanks for your all your help. James ---

I’ve seen several distinct Wpf and server apps climb steadily over periods as long as half an hour before eventually leveling out around 220 Meg… I think that’s just normal 🙂 ---
