Howdy, Look at your logs for errors, including OutOfMemoryErrors. Determine what is the maximum expected load your application needs to handle, and then determine the memory your application requires in order to handle that load with acceptable response times. Create test scripts to stress test your application up to the maximum expected load. Profile and tune your application and your server until you can handle the load in a satisfactory manner.
If this seems like a generic answer, that's because it is, as is your question. This has been discussed many many times on this list in the past: you can search the archives for more details.
