Tomcat optimizations

Are there any recommended tomcat optimizations for running a Jruby rails app under Tomcat ?  been getting some heap memory errors and figured i would ask the community as I go through some tuning and tweaking of memory allocation.

Thanks

Tomcat has a history of memory management problems. Try to run your
application on Jetty and see if you find the same issues, if you do,
it's probably something wrong with your code.

Thanks, not exactly the response I was looking for, though.  Enterprise standard here is to run under Tomcat which is why I am leveraging Jruby (to fit within enterprise standards of our Application server) and was just seeing if anyone had some recommended optimizations for using Jruby with Tomcat.

I am currently using the default configuration of Tomcat which is fairly unaggressive in memory allocation so I wanted to get some feedback before moving forward with my customizations.

Hi Adam,
i run jruby scipts in my regular java apps on tomcat without problems,
things You can experiment with are:
-Xms
-Xmx
-XX:MaxPermSize
and for sure turn on -XX:+PrintGCDetails, but all of these are jdk
related not tomcat related.
Also You can read more about it here:

Best greetings,
Paweł Wielgus.
