JRuby 1.5.0.RC1 + Rails3: OutOfMemoryError: Java heap space

Ruby JRuby
1

Hi guys,

So I have just finished upgrading a simple rails app to rails 3 and am
getting the following stack trace when starting up with tomcat (also
tested on jetty):

Does it ring any bells?

If not, I can prepare a test app and send it to the list to see if
someone can give me a hand.

Thanks,

Leonardo Borges

Not using Rails 3 yet, but I’ve been unable to get any JRuby/Rails app
to run on any container with rack 1.1.0 – you might try dropping in
1.0.1.

FWIW,

I just created an rails-3.0.0.beta4 application, scaffolded a simple
model, created war file and deployed it on jetty. all went smooth. and
it uses rack-1.1.0, sqlite3 and everything is on linux.

without further info (test application) I can not tell more.

regards Kristian

The stacktrace shows you are running out of heap space. How much does
tomcat have? Have you tried increasing it? If there are other webapps
running on tomcat this could be reducing the amount available for the
app with the error.

Take a look at: http://wiki.apache.org/tomcat/FAQ/Memory

Hmm Apparently Rails 3 requires rack 1.1.0 so I cannot easily downgrade
rack :S

I’ll keep looking but if you have any other ideas please do let me
know…

Cheers,
