I am now struggle on Jruby on Rails. We did not config the min/max jruby runtime before, the portal works well.
In these days, i found that set these config will improve our portal's performance, so I decide to config it in this way:
config.webxml.jruby.min.runtimes = 2
config.webxml.jruby.max.runtimes = 4
However, we portal can not boot up after i setting this, the log continue throw the java class can not found error:

What is the difference when we set this min/max jruby runtime? Anyone can get me out of this?
Thanks in advance.
