Dude, just do this... on the command line where you run java ..... com.yourstuff.YourClass add this parameter -Xrunhprof:file=java.hprof.txt,heap=all,format=a,doe=y Look at the end of the file. It will have all the objects allocated/deallocated. Run your program for a while. Look for the objects that get allocated but NEVER deallocated. These are many times static objects like singletons and such that don't clean up well. enjoy, Michael Lee Architect Afterbot [EMAIL PROTECTED]
