java.lang.OutOfMemoryError: Java heap space using jre 1.6.0

Hi,I try to use a SAX parser to read a XML document (about 400MB).With jre 1.5.0 everything ist fine. Now I tried to use jre 1.6.0 and geht this OutOfMemoryError.Can you tell me how to fix this problem?thx

There is a possibility that the GC ergonomics has changed it's behavior in the 6.0 release. Try specifying the heap size explicitly with an -Xmx command line key.Igor Veresov, Hotspot GC

I think i forgot to tell that i run the program with 420MB heap space in both cases. More is simply not possible on my system.Perhaps someone has another idea what else to do?!

420 MB total heap for a 400 MB XML file doesn't seem to be very much. But if it really runs with 5.0, you might want to try to set the New Generation to a fixed (rather small) size, leaving more space for the Old Generation.

Try to add

-XX:NewSize=8M -XX:MaxNewSize=8M

to your parameters. (8M is just a guess...)

I don't think that 420Mb is not very much for reading the XML file because I'm using a SAX Parser which doesn't load the complete file.In 5.0 it is also running with fewer HeapSpace.However I tried what you suggested but unfortunately this doesn't work either.

I had a similar problem (see the stack trace below). There is a known bug

(http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6536111) in this

regard. As a workaround I had to skip the DOCTYPE declaration from

the input stream and then let the parser parse the remaining stream

content.
