This does not look like a size problem. Maybe your file is still
opened when you try to open it again?

The limit on file sizes is imposed by your hardware and/or OS.
However your approach won't allow you to write more that the
amount of RAM you have since you use DOM and it keeps all the
data in memory.


> how i can write more than this limit?

One approach would be to open a new log file when the the current
file has grown too large. If you must keep everything in one file
then you can use DOM to serialize just one record instead of the
whole document. With this approach you will need to write the
head and tail of your document by hand and set the option on
DOMWriter not to write the XML declaration. I've described this
method in a bit more detail in a post to the Xerces-C++ mailing
list:
