Don't forget that the amount of memory your Java application uses at any given moment is not necessarily how much it needs. Instead of occasional memory leaks which happened to sloppy C++ programmers, in Java everything is a memory leak, but there is a recovery mechanism. So, if you let your Java program use 1GB of RAM, it WILL fill all of it with garbage before HAVING to do garbage collection. So, don't use your TaskManager figures as a measure of Cocoon/Tomcat's memory consumption.
If you are running a JProbe or an equivalent package, you can get an accurate reading of how much emory is actually used just after you trigger garbage collection. You can also trigger GC programmatically as well: Runtime.getRuntime().gc(); System.err.println(Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) ; Search through the mail archive to see where you can put -Xmx<upthewazoo>M option to the JVM. -- Ilya Barbara Post wrote: >Suddenly my sitemap doesn't compile.
