Sun Java 5 automatic heap size dimensioning does not know about the memory management of a Linux virtual server instance and therefore fails to get the size right. Even simple calls like "java -version" or the installation by your Linux distribution package manager does fail.
Solutions for these kind of problems are given.
To host your Grails / Java web application on a dedicated or virtual server (vServer) you'll need to know how much main memory your application needs and how much heap space is available to your application in a known environment. I'll give you formulas I derived from extensive experiments and rule of thumb for calculation with examples.[Read More]
