Sure, ptolemy-hackers is a good place to report problems. > I am having trouble with PtII-5.0-beta throwing "OutOfMemory" > Exceptions after the second or third run of a simple SDF model. > PtII-4.0.1 does not have this problem. Are you running from the prebuilt Windows installer under Windows? Or, did you recompile from scratch. If so, on what platform? What sdf model are you running? Is it one of the demos we ship, or a model of your own? Note that if you compiled Ptolemy II by hand, then you can run $PTII/bin/vergil -v which will show you the command line that Ptolemy II started with. One of the arguments should be "-Xmx256M" which limits the maximum memory size to 256Mb If you are running Ptolemy II using the Windows installer, the memory sizes are set in the *.lax files. For example vergil-full.lax sets the memory size for the "vergil-full" command. > I suspect the new beta has a memory leak somewhere, which I did not > know was possible with Java. Java has Garbage Collection, so you need not free memory explicitly, it should "just work: If an object has a references to it, then it might not be eligible for garbage collection and thus might be a leak. There are lots of ways to leak memory. See http://www.javaworld.com/javaworld/javaqa/1999-08/04-qa-leaks.html There are a few notes about memory leaks in $PTII/doc/coding/performance.htm or http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII5.0/ptII5.0-beta/doc/coding/performance.htm If you use Eclipse, then this plugin might be of use: http://sourceforge.net/projects/eclipsecolorer _Christopher Christopher Brooks (cxh at eecs berkeley edu) University of California Programmer/Analyst Chess/Ptolemy/Trust US Mail: 558 Cory Hall #1770 ph: 510.643.9841 fax:510.642.2739 Berkeley, CA 94720-1770 home: (F-Tu) 707.665.0131 (W-F) 510.655.5480 (office: 400A Cory) ---------------------------------------------------------------------------- Posted to the ptolemy-hackers mailing list.
