java.lang.OutOfMemoryError

Open patrickhno opened this issue 14 years ago • 5 comments

Suddenly cucumber stopped working, and there really isn't any good way to debug into the java stuff. It fails on the very first step (Given I am on ...) I takes forever before it barfs.

You will see versions in the stack trace. We would very much like to use akephalos so if there is anything we could tweek right away feel free to come with sugestions. We have allready invested into rewriting our framework to use the akephalos and it's just mind blowing it suddenly stopped working. But I guess that's how it is with memory and heaps. Once the threshold is passed, nothing works.

I changed -Xmx128M to -Xms512 and it resolved the issue for me. Id be happy to commit if I knew how to attach code to this issue :-)

java_args = [
  "-Xmx512M",
  "-cp", [JRubyJars.core_jar_path, JRubyJars.stdlib_jar_path].join(":"),
  "org.jruby.Main"
]

You can use this fork https://github.com/Nerian/akephalos. It gives more memory to the JVM.

Java is so perfect.. Should'nt this really be a option? I hardcoded the changes myself for now.

patrickhno avatar Jun 30 '11 11:06 patrickhno

That's is a nice idea. I will look at the code this afternoon.

@patrickhno

I gave it a try and cooked this.

https://github.com/Nerian/akephalos/tree/jvm

Akephalos' tests pass but I haven't a full app using akephalos to try this. Does it work in your app?:

Gemfile.

gem 'akephalos', :git=>'git://github.com/Nerian/akephalos.git', :branch => 'jvm'

spec_helper.

Capybara.register_driver :akephalos do |app| 
  Capybara::Driver::Akephalos.new(app, :jvm_max_memory => '512')
end
