Google Drive API stuck when uploading large file

Question

When I am uploading files, sometimes it will stick on a large file for much longer than it is supposed to. It uploads the previous files ok, but it always gets stuck at this 26MB file. The upload should only take 3 minutes, but it runs for 3+ hours, uses maximum upload bandwidth in Task Manager, and errors with 403 Unauthorized or 'java.io.IOException: unexpected end of stream' - just random errors. I'm uploading to a Google service account using a private key. I'm using Google Eclipse plugin, and added Drive API via Eclipse plugin. The only thing I can think of is to run it through Fiddler2/4 proxy to troubleshoot, but I shouldn't have to do that.

Code

        BufferedInputStream bis = new BufferedInputStream(new FileInputStream(f));
        System.out.println("type of file "+f.getName()+":"+type + ", length:"+f.length());
        File driveFile = DriveService.insertFile(name, type, Constants.DOC_TYPE_PRIMARY, bis);

public static File insertFile(String name, String type, String docType, InputStream inputStream) throws IOException, Exception
{
    File file = new File();
    file.setTitle(name);
    file.setMimeType(type);
    file.setDescription(docType);

    List<ParentReference> parents = new ArrayList<ParentReference>(); //create parent ref
    parents.add(new ParentReference().setId(Constants.DRIVE_FOLDER_IDS.get(docType)));
    file.setParents(parents);

    InputStreamContent isc = new InputStreamContent(type, inputStream);
    File retval = getService().files().insert(file, isc).execute();

    //apply domain reader access
    enableDomainReaderAccess(retval.getId());

    return retval;
}
