No, this isn't right: the properties you are talking about are for the batch process itself (on a win32 machine). When startup.bat calls "java", those values are not inherited by the VM. > Do I simply increase the value after 'Xmx' in the JAVA_OPTS variable > in catalina.sh file? This ought to work for you. Although it is not unheard of to legitimately run out of memory (i.e. get OutOfMemoryErrors), you ought to think about whether or not increasing your heap size is actually going to fix your problem: often, you have a memory leak and it's better to test your app with a small heap because you can find it more quickly (i.e. less memory to burn through before you run out). I strongly advise you to critically examine your code to determine if the OutOfMemoryErrors are being caused by you, or if you really do just need more memory allocated to the JVM. -chris
