Thanks for responding as I wasn't sure you would read down to the bottom and I slipped by putting the editorial above the information :) I think I had also seen the answer posted prior to making my reply so it was a bit of a biased approach but I think the strategy is generally good. Of course, "close" would also be something to look for. I've never used them but there are heap dump tools that should be able to give you some suspects. In fact, I just tried jhat on a contrived case and you may want to post output from this in the future ( "why do I have 100,000 pdfwriters? LOL): http://java.sun.com/javase/6/docs/technotes/tools/share/jhat.html http://www.google.com/search?hl=en&q=java+heap+dump+site%3Asun.com&btnG=Google+Search&aq=f&oq= 467 java -XX:+HeapDumpOnOutOfMemoryError x 470 jhat java_pid3628.hprof 472 history | tail | unix2dos> /dev/clipboard I opened a browser to 127.0.0.1:7000 and got a heap dump showing the biggest memory offenders ( or course lynx would have worked as well as firefox). I've been developing on wireless and forget these things are available and this worked on the first try :) > > > Pradeep > In this case, I just grepped the source code for "memory" and > does look like there are reasonably good comments about this issue > in many places.
