> Key: FILEUPLOAD-307
> URL: https://issues.apache.org/jira/browse/FILEUPLOAD-307
> Project: Commons FileUpload
> Issue Type: Bug
> Affects Versions: 1.4
> Reporter: Fernando Hartmann
> Priority: Major
>
> Some exceptions in FileUploadBase.parseRequest you can leave Request InputStream open, leading to a memory leak, because FileItemIteratorImpl InputStream is not closed.
> In my case the following Exception generates the problem.
>
> {code:java}
> Caused by: java.io.EOFException: Unexpected EOF read on the socket
