Hi,
any comment on this "out of memory" with large file upload?
This error seems recurring to a bunch of users, but I'm wondering if it's a
problem in the tomcat implementation, or if there are other layers to blame.
Thanks for any light on this darkness, since I've a tight schedule on
this issue... unfortunately..
cheers,
fabrizio

Subject: Uploading large files - out of memory exception
Dear tomcat developers,
I've noticed a problem while uploading files with tomcat 4.1.x.
- When uploading large files (say larger than 10MB) tomcat throws an out
of memory exception.
- The problem can be avoided raising the memory allocation (as found in
other similar messages, -Xms128m -Xmx512m) but this is not a solution,
since it depends on the memory and just makes the limit higher.
I do not know how the actual download works (we are using the
EchoPoint fileupload component, for that matters) but it seems that
the whole file is slurped in memory _before_ passing the request to a
user servlet. Indeed it seems that our download component is never
invoked (see the error below).
Is there a configuration option to avoid this behavior, or there's
nothing to do but limit the filesize?
Thanks in advance for any clue and
cheers,
Fabrizio
