I'm sorry but I don't know. I can just tell you that: * No other user/customer has reported memory leak problems. Out of memory problems: yes, memory leaks: no. * Java manages its memory within the limit specified using a command-line option (currently it's 512Mb). This means that [1] memory consumption will *never*, *ever*, exceed 512Mb, [2] the memory consumption must be monitored using Java tools and not system tools. Menu item "Help|About" performs a garbage collection and then reports simple memory statistics. If you do that several times after closing all documents, you'll see that memory consumption will go down (at the Java level, not at the OS level). JConsole, part of the JDK, can be used to connect to a running Java 1.6+ application and monitor many application parameters, among them the memory consumption. > > I noticed this only because I’m trying to reproduce a reported problem > with XXE crashing when editing a document having many small png icons > (~1Kb). I haven’t reproduced the problem, btw. > There are two, very different, kinds of crashes: * Java crashes: XXE window disappears. In such case, it creates a log file containing information about the JVM. There is nothing you or we can do in such case. Such crashes are generally caused by a bad graphics card driver. A possible workaround is to specify -Dsun.java2d.d3d=false on the XXE command-line (xxe.bat or xxe.jstart). * XXE crashes: XXE window does not disappear. A stack trace is printed on the console. You need to tell us how to reproduce the bug and/or send us what has been printed on the console.
