Firstly, running out of memory after a predictable period of running (rather than because of peak loading) suggests a memory leak. These are possible in Java if you hold onto object references accidentally once you're done with them (or libraries you call do so). If this is the case, adding more JVM memory won't help you. You may want to monitor your Java memory usage with the JVM profiler (or an external tool like jProbe). Assuming that this isn't the case, then you have the correct command line parameter - you're setting it to about 120 Mb in your example (which you can specify as "-Xmx120M" if you prefer). The default value for this is 64 Mb on Solaris and WinNT with Sun's JVM.
