Hi,
I think I know the problem. This is not a thread safety but a lack of
Ruby runtime available. I don't think you can configure that value with
v3, but with Grizzly 1.5 you can by doing:
% java -jar ruby-1.5.1.jar [port] [jruby applications] [number of
runtime] [asyncExecution=true|false]
When v3 ran out of runtime, it throws a 503 (heuk...will fix that as it
should park the request instead, waiting for a runtime to become
available). Try increasing the value using Grizzly 1.5 implementation
(that one will go into v3 this week). Hopefully you aren't facing new
problems :-)
Thanks
