Description

file uploads are a significant part of our web application and within our
application (running with default heap sizes under jdk 1.4.2) after a lot of
the error messages below we started getting OutOfMemoryErrors. I presume the
error below is coming from people who click 'stop' on their browser before the
upload has completed which is fine. I don't know whether it is another part of
the application that is causing the out of memory errors but I think it is
worth investigating the file upload code. Currently, we have increased the min
and max heap sizes to 256 and 512 Mb respectively so have not seen the problem
again, yet. We are using struts 1.1, html:form, html:file and
enctype="multipart/form-data" to do the file uploads and FormFile in the Java
ActionForm.
