1) Make sure that the app is using ServletRequest.getInputStream() 2) See the spec: 'SRV.4.1.1 When Parameters Are Available'

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

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?
