Hi all,
I'm using Clojure for web apps inside Tomcat. If I don't compile
my .clj files ahead of time, I will eventually get one of these
OutOfMemory errors, after a number of redeployments. Is there
something I can do about this? Is this a bug somewhere, in my code,
or in Clojure, or in Tomcat; or a limitation of the JVM?
thanks,
Rob
Here is the entire barfage from my Tomcat log:
