Hi,

Is there anybody with "out of memory" problems using FormFile in
Struts
1.2.4?

I've just migrated from 1.1 and I didn't change anything related to
file
attachment logic. But the actions that use "html:form" tag-lib with
enctype="multipart/..." and file attachment logic are now taking about
40MB
of RAM off in each request...after two or three clicks the garbage
works or
I receive "out of memory".

Is there any changes in the Struts "FormFile" approach after 1.1?

Thanks in advance!

Paulo Alvim
